ICTS summer school on GW astronomy

Applications are invited for the ICTS summer school on GW astronomy. This school is part of the annual ICTS summer schools on gravitational-wave (GW) physics and astronomy. Recent observations of nearly a hundred GW signals from coalescing binaries of compact objects have firmly established the field of GW astronomy. Physicists and astrophysicists are using these observations to not only study the properties of individual GW signals but also of the populations of these compact binaries as well as their progenitor stellar population. Recognizing this, this year's summer school will focus on foundational lectures on the astrophysics of GW sources, including the structure and evolution of stars that form progenitors of compact objects; and the evolutionary history of compact binaries and their population statistics. These lectures are organized into two graduate-level courses:

  • Stellar structure, evolution, collapse and supernovae: Anthony Mezzacappa (University of Tennessee, Knoxville, USA)
  • Compact binary evolution, rates and population modelling: Christopher Berry (University of Glasgow, UK)

The school is primarily meant for graduate students and postdocs in GW astrophysics and related fields. A small number of highly motivated senior undergraduates can also be considered. A basic understanding of general relativity and statistics is a prerequisite for the courses.

Lectures will be held online. Depending on the pandemic situations, we will consider the possibility of accommodating some of the participants at the ICTS campus so that the tutorials are conducted in person.

DATES: 30 May 2022 to 10 June 2022

LOCATION: ICTS, Bangalore + Online

IAU Symposium 368 - Machine Learning in Astronomy: Possibilities and Pitfalls

(Posted here March 4, 2022)

This IAU symposium, held August 2-4 2022 in Busan, South Korea, is under the broad umbrella of astroinformatics and astrostatistics but with an emphasis on the dissemination and demystification of deep learning techniques. We hope to encourage fusion of large datasets to enable exploration of combined parameter spaces that have so far remained unexplored. Using such diverse types as images, time series, spectra, and astrophysical simulations, one of our aims is to establish a list of reproducible "best-practices" solutions for astronomy data.

The symposium will also have sessions on more traditional machine learning, such as random forests, especially elucidating areas where deep learning is an overkill (and also sometimes ill-advised). We will supplement this with other astroinformatics sessions including those on methodology transfer to and from other science (e.g. Earth science, medical sciences etc.), visualization, simulations, astrostatistics and so on.

As things stand the symposium will be in-person and part of the IAU General Assembly in Busan.

Conference at KITP "Storming the Gravitational Wave Frontier"

(Posted here Jan 21, 2022)

Dear All,

some of you may be interested in attending the conference at KITP on April 19-23, 2022:

Storming the Gravitational Wave Frontier

The detection of gravitational waves by Advanced LIGO/Virgo has opened a new frontier in physics, with impact on areas ranging from field theory through stellar evolution and cosmology. It has also seeded new connections between theoretical communities, especially between field theorists and classical relativists. An even brighter future lies ahead, with more sensitive ground-based detectors and, eventually, a space-based observatory. Current and future experiments demand precision modeling of gravitational-wave signals in order to interpret the strongest gravitational-wave events and to enable sensitive searches for new physics which may be embedded in these signals. The conference will bring together experts from three communities: classical relativity, effective field theory, and scattering amplitudes. Building on the current state of the art, we will discuss the needs of the next generation of gravitational-wave experiments; identify which challenges theory must overcome; highlight recent advances in gravitational wave modeling for more detailed study; and uncover the most promising emerging tools and techniques from classical and quantum field theory for further development.

which is part of the 4-month KITP program: High-Precision Gravitational Waves (

Members of the gravitational wave community are invited to nominate students who have performed notable research on any aspect of gravitational wave science. Theses will be judged on 1) originality and creativity of the research, 2) importance to the field of gravitational waves and gravitational wave detection, broadly interpreted, and 3) clarity of presentation. The winner will receive a certificate of recognition and a prize of US$ 1,000. We aim to award the 2021 prize at a relevant conference in 2022. Depending on the situation, we may be able to offer support for travel (up to US$ 1,000) to receive the prize in person.

Eligibility: In this cycle, the prize will be awarded on a calendar year basis for 2021. The theses should have been accepted by their institutions between 1 January 2021 and 31 December 2021. It is expected that many of the nominations will come from the member projects of GWIC, but this is not a requirement. Nominated theses may be in any language. A committee selected from the gravitational wave community will evaluate the nominations and select the winner. The selection committee will make all determinations about eligibility.

Nominations: Nominations should be submitted by 31st January 2022. The nomination package consists of (i) the thesis, (ii) a letter of nomination, preferably from the thesis advisor, and (iii) a supporting letter from another scientist familiar with the work, and iv) an 1-2 page abstract of the thesis written by the nominee. The nomination and supporting letters should describe the importance and novelty of the research and the student’s particular contribution.

Electronic submission of the thesis and letters is strongly preferred, with the thesis, abstract and the letters in separate pdf files (4 files in total). Electronic copies of the nomination materials may be sent to Martin Hewitson <>. All submissions will be acknowledged; if an acknowledgement is not received shortly after the deadline, please contact Martin Hewitson <>. Please also provide a contact email address, and current institution for the nominee in the nomination letter.

If electronic submission is impossible, please contact Martin Hewitson <> for instructions concerning paper submission, or for any other concerns or queries.

Finally, we are aware that due to COVID, it is highly possible that thesis plans could be delayed, and in some cases formal extensions to thesis submissions may be in place in certain institutions. Please let us know if such delays and extensions affect any students you would otherwise nominate. Our preference at the moment is to continue with the normal schedule for the prize, but if there is significant evidence that a delay to the process would be appropriate, we will consider it.
