The presentation discovers observational capabilities and limitations of Maidanak observatory. It provides detailed information about the two 60 cm Zeiss telescopes – NT-60 and ST-60 and cameras installed on their foci. Because of smaller aperture, these telescopes have magnitude limitations and are not suitable for observations of faint objects. Installation of a new fast telescope devoted to...
I will present "Modelling the host galaxies of binary compact object mergers with observational scaling relation".
After the discovery of gravitational waves we saw that there must be black holes of different masses in the compact binaries, including the ones having fairly high masses. The remnant masses observed to date in the BBH mergers range from 17 to 170 solar masses.
In my presentation I will discuss the possibilities of what type of CBs could be their progenitors.
The results of the study of photometric observation material obtained in June 2021 with a CCD photometer in the 60-cm telescope of the Shamakhi Astrophysics Observatory named N.Tusi of Wolf 134 type WR 134 star are given. Observations of the star WR 134 were made in filter V of the international UBV photometric system and its short-term (approximately one hour) photometric variability was...
The evolution and death of massive stars and their effect on the surrounding objects is still an open question in astronomy. The type of Supernova that a star will undergo at the end of its life cycle depends on the mass-loss history of the star. Stars with similar initial mass might end up having different types of end evolution phases and die by different types of supernovae (SNe) processes....
Multi-messenger astronomy is a vast and expanding field as electromagnetic (EM) observations are no longer the only way of exploring the Universe.
Due to the new messengers, astrophysical events with both gravitational waves (GWs) and EM emission are no longer a dream of the astronomical community.
A breakthrough for GW multi-messenger astronomy came when the LIGO-Virgo network detected a GW...
In light of the importance of multi-wavelength characterization of gravitational wave sources, fast parameter inference of gravitational waves is a necessity. However, traditional methods like MCMC take several days to weeks for full parameter inference of GWs. After the promise of GW170817 and the associated multi-wavelength follow-up, the LVC promises several more such detectionsin the...
The search for kilonovae, either serendipitously or following a short gamma-ray burst (SGRB) or a gravitational-wave (GW) signal, has become a hot topic in astronomy in general, and multi-messenger astronomy (MMA) in particular. Efforts can be conducted with a variety of instruments (optical or near-infrared, where light curves and timelines are most conducive) and methods (filtering, fixed or...
The discovery of the optical/infra-red counterpart to the neutron binary merger gravitational wave detection (GW170817), which followed a short gamma-ray burst (GRB170817), was a groundbreaking moment in multi-messenger astronomy. It is, to date, the only confirmed joint detection of its kind, though many projects are currently developing wide-field surveys to find more electromagnetic...
I will give an overview of recent - and confusing! - research on merger-induced GRBs, especially the ultra-bright even GRB 211211A, which seems to combine a photometric kilonova detection with a temporally long GRB.
A presentation of the technological aspects of the camera, and their interest in astronomical observations with the T1M at Pic du Midi.
Use of the combined lin/log and non destructive readout modes for noise reduction and HDR.
COLIBRI is one of the ground follow-up telescopes under French responsibility especially developed for the SVOM mission, for the gamma-ray burst science and transient exploration. This 1.3 m telescope comes from a collaboration between France and Mexico and it will be commissioned and installed at the Observatorio Astronómico Nacional (Mexico) by the end of 2022/beginning 2023. It will have an...
