Atmospheric Conditions within Big Telescope Alt-Azimuthal Region and Possibilities of Astronomical Observations

open access: yesRemote Sensing, 2022
The paper presents the results of analysis of astroclimatic conditions in the Big Telescope Alt-azimuthal (BTA) region (40°N–50°N; 35°E–55°E). Using data from the European center for medium-range weather forecast ReAnalysis (ERA-5), we estimated the ...

First M87 Event Horizon Telescope Results. V. Physical Origin of the Asymmetric Ring [PDF]

open access: yesAstrophysical Journal, 2019
The Event Horizon Telescope (EHT) has mapped the central compact radio source of the elliptical galaxy M87 at 1.3 mm with unprecedented angular resolution. Here we consider the physical implications of the asymmetric ring seen in the 2017 EHT data.

Fermi Large Area Telescope Fourth Source Catalog [PDF]

open access: yesAstrophysical Journal Supplement Series, 2019
We present the fourth Fermi Large Area Telescope catalog (4FGL) of γ-ray sources. Based on the first eight years of science data from the Fermi Gamma-ray Space Telescope mission in the energy range from 50 MeV to 1 TeV, it is the deepest yet in this ...

Hammering with the telescope

open access: yesFrontiers in Artificial Intelligence, 2022
The rapid pace in which various Artificial Intelligence and Machine Learning tools are developed, both within the research community and outside of it, often discourages the involved researchers from taking time to consider potential consequences and applications of the technical advances, especially the unintended ones.

The Australia Telescope National Facility Pulsar Catalogue [PDF]

open access: yes, 2003
We have compiled a new and complete catalog of the main properties of the 1509 pulsars for which published information currently exists. The catalog includes all spin-powered pulsars, as well as anomalous X-ray pulsars and soft gamma-ray repeaters ...

Black holes with scalar hair in light of the Event Horizon Telescope [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2020
Searching for violations of the no-hair theorem (NHT) is a powerful way to test gravity, and more generally fundamental physics, particularly with regards to the existence of additional scalar fields.

Neutrino Telescopes [PDF]

open access: yesAIP Conference Proceedings, 2006
The observation of high energy cosmic neutrinos can shed light on the astrophysical sites and mechanisms involved in the acceleration of protons and nuclei to the high energies observed at Earth by cosmic ray detectors. More generally, high energy neutrinos can be a key instrument in the multimessenger study of the high energy sky.

Probing Diversity of Type II Supernovae with the Chinese Space Station Telescope

open access: yesUniverse, 2023
Type II supernovae (SNe II), which show abundant hydrogen in their spectra, belong to a class of SNe with diverse observed properties. It is commonly accepted that SNe II are produced by core collapse and explosion of massive stars.

Science case for the Einstein telescope [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2019
The Einstein Telescope (ET), a proposed European ground-based gravitational-wave detector of third-generation, is an evolution of second-generation detectors such as Advanced LIGO, Advanced Virgo, and KAGRA which could be operating in the mid 2030s.
