Local Heavily Obscured Active Galaxies Observed With Chandra (I): Spectral Properties of the Nuclear and Extended X-ray Emission
R. Middei, G. Fabbiano, A. Trindade Falcão +3
The Chandra X-ray Observatory has revealed that kiloparsec-scale extended X-ray emission is commonly associated with heavily absorbed (/cm) Active Gala…
Active Galactic Nuclei-driven Metallicity Enrichment in the Interstellar Medium of Mrk 573
D. Ł. Król, P. Zhu, G. Fabbiano +5
We present the first spatially resolved at pc scale application of AGN-specific metallicity diagnostics for the nearby Compton-thick Seyfert 2 galaxy Mrk 573 ()…
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…
The X-ray Emission of NGC 5005: An Unobscured Low-Luminosity AGN with a Weakly Accreting Broad-Line Region
Anna Trindade Falcão, R. Middei, G. Fabbiano +5
We present deep Chandra X-ray observations of NGC 5005, a LINER-dominated galaxy previously reported to host a broad H emission line. The diffuse soft X-ray emission (3 keV)…
Mapping the Excitation Mechanisms in the LINER I Active Galactic Nucleus NGC 5005: Positive Feedback and a Thin LINER Cocoon
Anna Trindade Falcão, G. Fabbiano, M. Elvis +5
We present a spatially resolved Baldwin-Phillips-Terlevich analysis of the narrow-line region (NLR) in the low-ionization nuclear emission-line region (LINER) I galaxy NGC 5005 usi…
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…
