47. Readiness of Maidanak observatory to the observations of optical transients during the O4 run

Dr Yusufjon Tillayev (Ulugh Beg Astronomical Institute)

30/05/2022 16:30

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...

56. Modelling the host galaxies of binary compact object mergers with observational scaling relation

M. Filippo Santoliquido

30/05/2022 16:50

I will present "Modelling the host galaxies of binary compact object mergers with observational scaling relation".

40. Which CBs could be transformed in the known sources of GWs

Dr Nino Kochiashvili (Abastumani Observatory, Georgia)

30/05/2022 17:10

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.

44. WOLF RAYET TYPE WR 134 STAR SHORT-TERM PHOTOMETRIC VARIABILITY

SHABNAM AGHAYEVA (GRANDMA)

31/05/2022 09:10

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...

48. Probing Mass Loss Properties of Supernova Progenitors

Mlle Priyadarshini Gokuldass (Florida Institute of Technology)

31/05/2022 09:30

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....

54. Processing of observational data with AbAO-T70

Sophia Beradze

31/05/2022 09:50

As part of the project Grandma, we will talk about photometric processing of observation data obtained using the 70 cm Meniscus telescope of the Abastumani Astrophysical Observatory. To improve data processing we will talk about what difficulties may arise during processing and ways to solve it. Abastumani Team is ready for the upcoming O4 observational run.

42. Search for GW in coincidence with burst sources during 03

Iara Tosta e Melo (INFN LNS)

31/05/2022 10:40

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...

49. swyft Parameter Inference of Gravitational Waves using Machine Learning

Uddipta Bhardwaj (GRAPPA, University of Amsterdam)

31/05/2022 11:00

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...

36. Optimization Simulations for Kilonova Detections in Optical and Near Infrared

Nidhal Guessoum (American University of Sharjah, Physics Department)

31/05/2022 11:20

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...

34. Effect of Vera C. Rubin Observatory Filter and Return Time Selections on Kilonovae Detectability

Cristina Andrade (School of Physics and Astronomy, University of Minnesota)

31/05/2022 11:40

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...

45. ShaO observations T-Tauri and methods for the photometry

Zumrud Vidadi (SHAO)

01/06/2022 09:15

In this report we have presented some results of analysis of the light variation of the star DG Tau, based on 582 nights UBVR photometric observations. We have shown that both the average annual and seasonal values of the star's brightness varies for all photometric bands. The amplitude of the seasonal change in the V band is at 1 mag, and in 50 years, it is nearly 2 mag. Color-dependent...

31. GRB 211211A - The Attesor Acid GRB

Dr David Alexander Kann (IAA-CSIC)

01/06/2022 09:35

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.

39. SIRIS, a ultra low noise and ultra high dynamic SWIR camera

Julien Dubouil (IMCCE)

28. Fast detection and follow-up of high energy transients with COLIBRI

Simona Lombardo (Aix Marseille Univ, CNRS, CNES, LAM, Marseille, France)

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...
