Testing alternative theories of gravity by fitting the hot-spot data of Sgr A*
European Physical Journal C: Particles and Fields, 2022 We are fitting dynamics of electrically neutral hot-spot orbiting around Sagittarius A* (Sgr A*) source in Galactic center, represented by various modifications of the standard Kerr black hole (BH), to the three flares observed by the GRAVITY instrument ...

GALACTIC CENTER MINISPIRAL: INTERACTION MODES OF NEUTRON STARS
Acta Polytechnica, 2015 Streams of gas and dust in the inner parsec of the Galactic center form a distinct feature known as the Minispiral, which has been studied in radio waveband as well as in the infrared wavebands.

Precession of timelike bound orbits in Kerr spacetime
European Physical Journal C: Particles and Fields, 2021 Astrometric observations of S-stars provide a unique opportunity to probe the nature of Sagittarius-A* (Sgr-A*). In view of this, it has become important to understand the nature and behavior of timelike bound trajectories of particles around a massive ...

The Variability of Sagittarius A* at Centimeter Wavelengths
The Astronomical Journal, 2004 We present the results of a 3.3-year project to monitor the flux density of Sagittarius A* at 2.0, 1.3, and 0.7 cm with the VLA. The fully calibrated light curves for Sgr A* at all three wavelengths are presented. Typical errors in the flux density are 6.1%, 6.2%, and 9.2% at 2.0, 1.3, and 0.7 cm, respectively.

The Astrophysical JournalWe develop a new method for studying the Galactic magnetic field along the spiral arms using pulsar Faraday rotation measures (RMs). Our new technique accounts for the dot-product nature of Faraday rotation and also splits the associated path integral ...

The Multifrequency Behavior of Sagittarius A* [PDF]
Proceedings of XII Multifrequency Behaviour of High Energy Cosmic Sources Workshop — PoS(MULTIF2017), 2018 The Galactic Center is the closest galactic nucleus that allows us to determine the multi-frequency behavior of the supermassive black hole counterpart Sagittarius A* in great detail. We put SgrA*, as a nucleus with weak activity, into the context of nearby low luminosity nuclei.

On the Structure of the Sagittarius Spiral Arm in the Inner Milky Way
The Astronomical JournalWe report measurements of trigonometric parallax and proper motion for two 6.7 GHz methanol and two 22 GHz water masers located in the far portion of the Sagittarius spiral arm as part of the BeSSeL Survey.
