3rd HEL.A.S. SUMMER SCHOOL AND DAAD SCHOOL

NEUTRON STARS AND GRAVITATIONAL WAVES

OCTOBER 8-12, 2018
THESSALONIKI, GREECE

Important dates: Early registration: 20/8/2018 ; Late registration: 10/9/2018

SECOND ANNOUNCEMENT

With the detection of the binary black hole merger GW150914, we have entered the era of Gravitational Wave Astronomy, while the detection of the binary neutron star merger GW170817 was the first example of Gravitational Wave Multi-messenger observations. In the coming years, additional science runs with the LIGO and VIRGO detectors are expected to lead to exciting new discoveries, with KAGRA and LIGO-India subsequently joining the existing detectors and forming a global network. In parallel, new upgrades and new detectors are planned, whereas space-born gravitational wave detectors, such as LISA, are under intense development.

The main goal of this school is to provide an introduction to the foundations of Gravitational Waves, including theory, numerical simulations, principles of detection and astrophysical implications. Neutron Stars will be discussed in detail as one of the prime sources of gravitational waves, emphasizing the key role that gravitational wave astronomy can play in constraining the theory of gravity observationally.

The Aristotle University of Thessaloniki will welcome around 30 MSc and PhD students to attend the summer school, which will introduce them to key concepts in this exciting field as well as provide them with an opportunity to interact with experts. Advanced undergraduate students that are engaged in research projects related to the theme of the summer school may also apply.

The program of the summer school will consist of several 90’ minutes lectures on each morning, with additional exercise-style lectures and talks by members of the DAAD collaboration on each afternoon. Indicative titles for the lectures are:

1) Theory of gravitational waves
2) Compact object oscillations and GW asteroseismology
3) Constraints on the neutron star equation of state
4) Magnetars and core-collapse supernovae
4) Compact objects in alternative theories of gravity
5) GW detectors: LIGO/VIRGO and planned 3rd generation detectors
6) LISA mission and science

Fundamental physics with LISA, Florence, Italy

Posted on by

Observations of astrophysical systems where gravity is extreme — highly-dynamical and/or non-linearly strong — have the potential to shed light on some of the most profound questions in physics today: from the nature of compact objects to whether Einstein’s theory accurately describes the merger of black holes. The first space-borne detector, LISA, a joint ESA-NASA mission is currently planned to be deployed in 2034, allowing for the first observation of the merger of supermassive black holes and of extreme mass-ratio inspirals. These observations will enable new accurate tests of general relativity, in particular in the strong regime.

We announce the Fundamental Physics with LISA workshop which will take place on November 12-14, 2018 at the Galileo Galilei Institute (Arcetri, Florence, IT). Its goal will be to discuss ways in which we can test General Relativity and learn about fundamental theoretical physics with future LISA observations.

For more information and registration, please visit the conference webpage: http://www.ggi.infn.it/showevent.pl?id=305

In order to encourage interaction and discussion, the workshop will bring together experts in theory, phenomenology, modeling and data analysis, and will have an unusual format. Each day will be centered around one of these facets, and consist of three topical sessions in which discussions will be moderated by a panel of three or four experts. The goal of the workshop is to foster fruitful interactions between different dimensions of LISA science. This will include the following topics:

* Model independent tests versus Model-Specific tests of GR.
* Tests of GR and inferences about physics from the inspiral of supermassive black holes.
* Tests of GR and inferences about physics from the ringdown of supermassive black hole merger.
* Tests of GR and inferences about physics from extreme mass-ratio inspirals.
* Inferences about the nature of supermassive black holes.
* Tests of superradiance and inferences about ultralight boson fields and fuzzy dark matter.
* Exotic compact objects, tests of the horizon, and GW echoes.
* Environmental effects

The number of participants is limited. The registration deadline is *Sepember 1st* or earlier if the capacity of the conference venue is reached. The conference fee (€60) includes lunch tickets for on-site catering.

New code: EFTofPNG (version 1.0)

Posted on by

EFTofPNG is a public Mathematica code for high precision Feynman computation in the Effective Field Theory of Post-Newtonian Gravity. The code covers the current state of the art PN accuracy including spinning components in the merging compact binaries. Its final unit computes observables useful for the waveform modelling, and serves as a pipeline chain for the wave templates.

This package was created in view of the timely need to publicly share automated computation tools, which integrate the various types of physics manifested in the expected increasing influx of gravitational waves data.

The code is available as a public repository in GitHub.

We aimed for a code accessible to the classical Gravity community, yet of possible use to the broader community.

The Next Detectors for Gravitational Wave Astronomy, 5-week workshop, KITPC, Beijing

Posted on by

The first detection of gravitational waves by ground-based detectors in the 10Hz – 10 kHz frequency band is expected after advanced gravitational wave detectors now being installed and commissioned reach their full sensitivity, between 2016-2020. Signals from the known population of binary neutron stars are expected, as well as signals from other sources such as binary black holes. In addition to ground-based detectors, space based detectors for the millihertz band are under active development, pulsar timing observatories are searching for gravitational waves in the nanohertz band, and studies of the cosmic microwave background are searching for evidence for gravitational waves at ~10-16 Hz. The need for an expanded array of ground-based detectors is well understood. Expansion of the array and particularly the addition of a southern hemisphere detector will greatly improve angular resolution, array duty cycle, source galaxy identification, and source parameter estimation. The expanded array should be designed to maximise the science outcomes of gravitational wave astronomy in regard to both the fundamental testing of general relativity and astrophysical observations.

New approaches and new technologies for ground based gravitational wave detectors have been under development for a number of years. Proposed designs for future detectors were considered by the Einstein Telescope collaboration and by LIGO Scientific Collaboration “colour groups” in 2010-2012.

This KITPC Program will bring leading experts in gravitational wave astrophysics, gravitational wave detector science and engineering, quantum opto-mechanics, precision optics, fine mechanics and materials science together in a 5 week program focused on designing the next ground based detectors, and special sessions and workshops on the optimum design for space based detectors.

Future detector designs depend crucially on key enabling technologies in which there has been intense theoretical and experimental research over recent years. These include

– theory of acoustic noise and development of optical materials that combine ultralow acoustic noise and optical losses,
– theory and technology for Newtonian gravitational noise reduction,
– theory and implementation of macroscopic quantum measurement techniques.

Considerations for evaluating different detector arrays include: a) knowledge and modelling of signal sources; b) modelling of detector array performance in relation to source parameter extraction and signal to noise ratio; c) methods of data analysis; d) capabilities and performance of multi-messenger astronomy techniques.

Finally, design choices for the next ground based detectors will depend on practical considerations that include the time scale for achieving performance requirements, understanding of the risks associated with design choices, and cost trade-offs versus funding opportunities.

Week 1 will focus on the entire gravitational wave spectrum including regions targeted by pulsar timing, space laser interferometers, atom interferometers and ground based detectors. It will review the current knowledge of sources, detectors and data analysis, and identify critical areas of research in the physics of sources, gravitational wave detector science and multimessenger astronomy.

Week 2 will include the Third Beijing Workshop on Gravitational Waves (held at Tsinghua University, Beijing). The program of this workshop is centered on the following themes:

– Detection of gravitational waves: instruments, signal analysis, data analysis,…
– Gravitational wave sources: neutron star binaries, black hole binaries,…
– Multi-messenger astrophysics: optical, X-ray, or gamma ray counterparts, neutrinos,…
– Other gravitational-wave related themes (supporting computing architecture,…)

Weeks 3-4 will explore the possibilities for realistic designs for the next ground based detectors, plus workshop to explore space detector designs and their synergy with ground based detectors. Sessions will include:

– Quantum measurement technologies based on optical squeezing and optical spring effects;
– Core technologies including laser wavelength, test mass material, optical coatings, detector configurations, vacuum and cryogenics, and control systems.
– Broadening the sensitivity bandwidth (<10Hz, >3kHz) and multimessenger astronomy.
– Interferometer arm length: vacuum and cost/sensitivity trade-offs. Space detector workshop topics will include:
– Technology: high-power space qualified lasers, ultra-stable oscillators, pointing, sensors, UV discharging, time delay interferometry.
– Mission design: layout, armlength, orbit.
– Sources, data analysis and multimessenger astronomy: galaxy and black hole evolution, optical counterparts, EMRI templates, TeV signatures and dark energy.

Week 5 will focus on the programme outcomes: completion of the science case and conceptual design for the next ground based detectors. Publication: The outcomes will be published as a special issue of a refereed journal containing a single multi-authored design paper on the next ground based detector, a multi-authored review on space detectors and short individual contributions. Week 5 will also organize an international conference on gravitation and cosmology jointed with the 4th Galileo-Xu Guangxi meeting, to celebrate GR 100

About 50 international participants and 100 participants from China are expected to attend the KITP Program, which will take place on the Campus of the CAS-KITP in Beijing. The program will include formal presentations, workshops and informal working groups along the lines of Aspen workshops. The draft program below will be modified according to advice from the IAC and Coordinating Committee and availability of participants. Funding details for participants will be given in the second announcement.

Towards gravitational wave astronomy: data analysis techniques and challenges, London

Posted on by

The next few years promise to be exciting ones for the field of gravitational wave astronomy: ground-based gravitational wave detectors will begin taking data at unprecedented sensitivities; pulsar timing arrays are continuing to improve their timing accuracy; and several experiments are studying the cosmic microwave background polarisation in great detail. Together, these methods are probing a huge range of the gravitational wave spectrum, and detections will offer a wealth of new information on compact binaries, supermassive black holes, and general relativity in extreme environments from the early universe to black hole mergers.
Exploiting the datasets provided by these cutting edge observations has spurred the development of novel data analysis methods to understand gravitational wave sources.

This Royal Astronomical Society discussion meeting will bring together researchers from these diverse areas to encourage the sharing of techniques and foster further collaboration within the data analysis community.
