tilepy: A Flexible Open-Source Scheduling Engine for Time-Domain and Multi-Messenger Astronomy
Fabian Schüssler, H. Ashkar, W. Kiendrébéogo +5
The era of multi-messenger astrophysics requires rapid and efficient follow-up of transient events, many of which, such as gravitational waves (GW), gamma-ray bursts (GRB), and hig…
tilepy: Smart Scheduling for Multi-Messenger Astronomy from Earth to Orbit
Halim Ashkar, Monica Seglar-Arroyo, Fabian Schüssler +2
The rise of direct detection of gravitational waves (GWs) started a new era in multi-messenger astrophysics. Like GWs, many other astrophysical transient sources suffer from poor l…
Cross-Observatory Coordination with tilepy: A Novel Tool for Observations of Multi-Messenger Transient Events
Monica Seglar-Arroyo, Halim Ashkar, Mathieu de Bony de Lavergne +1
Time-domain astrophysics has leaped forward with the direct discovery of gravitational waves and the emergence of new generation instruments for multi-messenger studies. The capaci…
Follow-up of gravitational waves alerts with IACTs using Astro-COLIBRI
Mathieu de Bony de Lavergne, Halim Ashkar, Atilla Kaan Alkan +4
Follow-up of gravitational wave alerts has proven to be challenging in the past due to the large uncertainty on the localisation, much larger than the field of view of most instrum…
Interpolation of Instrument Response Functions for the Cherenkov Telescope Array in the Context of pyirf
Rune Michael Dominik, Maximilian Linhoff, Julian Sitarek
The Cherenkov Telescope Array (CTA) will be the next generation ground-based very-high-energy gamma-ray observatory, constituted by tens of Imaging Atmospheric Cherenkov Telescopes…
, the scientific software for the Cherenkov Telescope Array -- NectarCAM
Guillaume Grolleron, Halim Ashkar, François Brun +8
The NectarCAM is a camera that will be mounted on the Medium-Sized Telescopes of the Cherenkov Telescope Array (CTA) observatory. Along with the hardware integration of the camera,…
Performance update of an event-type based analysis for the Cherenkov Telescope Array
Juan Bernete, Orel Gueta, Tarek Hassan +3
The Cherenkov Telescope Array (CTA) will be the next-generation observatory in the field of very-high-energy (20 GeV to 300 TeV) gamma-ray astroparticle physics. The traditional ap…
tilepy: rapid tiling strategies in mid/small FoV observatories
Fabian Schüssler, Halim Ashkar, Mathieu de Bony de Lavergne +1
The challenges inherent to time-domain multi-messenger astronomy require strategic actions so that adapted, optimized follow-up observations are performed efficiently. In particula…
The H.E.S.S. transients follow-up system
C. Hoischen, M. Füßling, S. Ohm +12
Observations of astrophysical transients have brought many novel discoveries and provided new insights into physical processes at work under extreme conditions in the Universe. Mul…
Astro-COLIBRI -- The COincidence LIBrary for Real-time Inquiry for multimessenger astrophysics
P. Reichherzer, F. Schüssler, V. Lefranc +4
Astro-COLIBRI is a novel tool that evaluates alerts of transient observations in real time, filters them by user-specified criteria, and puts them into their multiwavelength and mu…
Cross-calibration and combined analysis of the CTA-LST prototype and the MAGIC telescopes
Y. Ohtani, A. Berti, D. Depaoli +13
The Cherenkov Telescope Array (CTA) will be the next generation gamma-ray observatory, which will consist of three kinds of telescopes of different sizes. Among those, the Large Si…
The H.E.S.S. Gravitational Wave Rapid Follow-up Program during O2 and O3
Halim Ashkar, Francois Brun, Matthias Füßling +8
Since 2015, the direct detection of Gravitational Waves (GWs) became possible with ground-based interferometers like LIGO and Virgo. GWs became the center of attention of the astro…
Reconstruction of extensive air shower images of the first Large Size Telescope prototype of CTA using a novel likelihood technique
Gabriel Emery, Cyril Alispach, Mykhailo Dalchenko +3
Ground-based gamma-ray astronomy aims at reconstructing the energy and direction of gamma rays from the extensive air showers they initiate in the atmosphere. Imaging Atmospheric C…
