65. Multi-Messenger Online Data Analysis and Galaxy platform

Andrii Neronov

17/09/2024 09:00

Multi-Messenger Online Data Analysis platform (MMODA) and Galaxy platforms provide services for on-the-fly analysis of publicly available data astronomical and astroparticle data for a range of telescopes. The platforms also provide a possibility for users to add new services based on user-contributed analysis workflows formulated in the form of python notebooks.

66. Predicting the topics of a follow-up Astronomical Telegram using knowledge graphs and natural language processing

Andrei Variu

17/09/2024 09:15

We have developed an automatic pipeline to predict the topics of a follow-up ATel and to assign data-analysis workflows, that will be publicly available at https://www.astro.unige.ch/mmoda/. To achieve this, we have created an ontology of telescopes, observatories and instruments in order to detect them in Astronimical Telegrams. Studying the occurances of these telescopes in the ATels, we...

64. ACROSS: The Astrophysics CRoss Observatory Science Support Initiative

Jamie Kennea (Penn State)

17/09/2024 09:30

In October 2022, NASA HQ directed the Physics of the Cosmos program office initiated a study to identify requirements and formulate implementation options for a TDAMM Guest of Observer Facility, in response to Astro2020 TDAMM recommendations. Phase 1 of the study investigated the coordination of NASA space-based missions. As a result of this study, NASA approved a pilot program for The...

63. Fast Radio Burst Alerts : frb-voe and the CHIME/FRB Virtual Observatory Event Service

Thomas Abbott

17/09/2024 09:45

Discovered in 2007, fast radio bursts (FRBs) are luminous, millisecond duration radio bursts that have quickly become one of the most fascinating classes of radio transients. The progenitor of FRBs remains a mystery, however, through observations like that of the FRB-like bursts detected from a galactic magnetar, SGR 1935+2154, it has been shown that collaborative efforts from multiple...

69. Accretion and ejection in binary systems

Sylvain Chaty (Université Paris Cité)

17/09/2024 10:30

I will review accretion and ejection phenomena in low-mass and high-mass X-ray binary systems

72. Real-time data processing with KM3NeT

S. Celli, V. Cecchini, D.Dornic, F. Filippini, E. Giorgio, E. Le Guirriec, G. Illumina:, M.
Lamoureux, M. Mastrodicasa, J.Palacios Gonzalez, S. Le Stum and G. Vannoye

KM3NeT is a multi-purpose neutrino observatory currently being deployed at
the bottom of the Mediterranean Sea. It consists of two detectors, ORCA and
ARCA (for Oscillation and Astroparticle Research with Cosmics in the...

67. Constraining Astrophysical Observables using Gravitational Wave Background

Musfar Muhamed Kozhikkal

17/09/2024 11:00

Pulsar Timing Array (PTA) is close to detecting Gravitational Wave Background (GWB) in the frequency range of nHz to µHZ. We present an extended analytic model to describe the characteristic spectrum of the GWB using the merger rate of supermassive black hole binary (SMBHB) in the Universe. Astrophysical observables (Galaxy stellar mass function (GSMF), pair fraction, merger timescale and mass...

71. Investigate the impact of magnetar on the kilonova afterglow emission in short GRBs through late-time radio observations

Ankur Gosh

17/09/2024 11:15

The coincident detection of Gravitational Wave (GW~170817) and short Gamma Ray Burst (GRB~170817A) confirmed their common origin from the coalescence of binary neutron stars (BNS). Depending on the BNS masses and equations of state, the outcome could be a black hole or a millisecond magnetar. In the presence of a magnetar, a significant portion of its rotational energy is transferred to the...
