Probing AGN-ISM Feedback through Extended X-ray Emission in ESO 137-G034
D. Ł. Król, G. Fabbiano, M. Elvis +6
We present a detailed analysis of the X-ray emission of the Compton-thick (CT) AGN ESO\,137-G034 based on deep (\,ks) Chandra observations. As in other CT AGNs, the morpho…
Self-gravitating collapsing star and black hole spin-up in long gamma ray bursts
Agnieszka Janiuk, Narjes Shahamat Dehsorkh, Dominika Krol
Long Gamma Ray Bursts (GRBs) originate from the collapse of massive, rotating stars. We aim to model the process of stellar collapse in the scenario of a self-gravitating collapsin…
Possible Gravitational Microlensing Events in the Optical Lightcurve of Active Galaxy S5 0716+714
D. Ł. Król, Ł. Stawarz, J. Krzesinski +1
A well-known active galaxy of the blazar type, S5 0716+714, is characterized by a particularly high variability duty cycle on short-time scales at optical frequencies. As such, the…
Magnetization of Relativistic Current-Carrying Jets with Radial Velocity Shear
Dominika Ł. Król, Łukasz Stawarz, Mitchell C. Begelman +3
Astrophysical jets, launched from the immediate vicinity of accreting black holes, carry away large amounts of power in a form of bulk kinetic energy of jet particles and electroma…
X-ray Emission of the -ray Loud Young Radio Galaxy NGC 3894
K. Balasubramaniam, L . Stawarz, C. C. Cheung +6
The radio source 1146+596 is hosted by an elliptical/S0 galaxy NGC\,3894, with a low-luminosity active nucleus. The radio structure is compact, suggesting a very young age of the j…
Gamma-ray Bursts as distance indicators through a machine learning approach
Maria Dainotti, Vahé Petrosian, Malgorzata Bogdan +7
Gamma-ray bursts (GRBs) are spectacularly energetic events, with the potential to inform on the early universe and its evolution, once their redshifts are known. Unfortunately, det…
