The collimation of relativistic jets launched from the vicinity of supermassive black holes (SMBHs) at the centers of active galactic nuclei (AGN) is one of the key questions to un…
Forbidden Line Emission from Type Ia Supernova Remnants Containing Balmer-Dominated Shells
Chuan-Jui Li, You-Hua Chu, John C. Raymond +3
Balmer-dominated shells in supernova remnants (SNRs) are produced by collisionless shocks advancing into a partially neutral medium, and are most frequently associated with Type Ia…
The Variability of the Black-Hole Image in M87 at the Dynamical Time Scale
Kaushik Satapathy, Dimitrios Psaltis, Feryal Ozel +235
The black-hole images obtained with the Event Horizon Telescope (EHT) are expected to be variable at the dynamical timescale near their horizons. For the black hole at the center o…
Measuring lens dimensionality in extreme scattering events through wave optics
Dylan L. Jow, Ue-Li Pen
Compact radio sources have been observed to undergo large, frequency dependent changes in intensity due to lensing by structures in the interstellar medium, in so-called "extreme s…
Investigating the Nature of the Luminous Ambiguous Nuclear Transient ASASSN-17jz
Thomas W. -S. Holoien, Jack M. M. Neustadt, Patrick J. Vallely +31
We present observations of the extremely luminous but ambiguous nuclear transient (ANT) ASASSN-17jz, spanning roughly 1200 days of the object's evolution. ASASSN-17jz was discovere…
Burst properties of the highly active FRB 20201124A using uGMRT
V. R. Marthi, S. Bethapudi, R. A. Main +7
We report the observations of the highly active FRb20201124A with the upgraded Giant Metrewave Radio Telescope at 550-750~MHz. These observations in the incoherent array mode simul…
A revised view of the linear polarization in the subparsec core of M87 at 7 mm
Jongho Park, Keiichi Asada, Masanori Nakamura +5
The linear polarization images of the jet in the giant elliptical galaxy M87 have previously been observed with Very Long Baseline Array at 7 mm. They exhibit a complex polarizatio…
Sub-second periodicity in a fast radio burst
FRB Collaboration, Bridget C. Andersen, Kevin Bandura +59
Fast radio bursts (FRBs) are millisecond-duration flashes of radio waves that are visible at distances of billions of light-years. The nature of their progenitors and their emissio…
The eROSITA Final Equatorial-Depth Survey (eFEDS): The first archetypal Quasar in the feedback phase discovered by eROSITA
M. Brusa, T. Urrutia, Y. Toba +18
Theoretical models of galaxy-AGN co-evolution ascribe an important role for the feedback process to a short, luminous, obscured, and dust-enshrouded phase during which the accretio…
The eROSITA Final Equatorial-Depth Survey (eFEDS): The AGN Catalogue and its X-ray Spectral Properties
Teng Liu, Johannes Buchner, Kirpal Nandra +23
Context: After the successful launch of the Spectrum-Roentgen-Gamma (SRG) mission in July 2019, eROSITA, the soft X-ray instrument aboard SRG, performed scanning observations of a…
The eROSITA Final Equatorial-Depth Survey (eFEDS): Identification and characterization of the counterparts to the point-like sources
M. Salvato, J. Wolf, T. Dwelly +41
In November 2019, eROSITA on board of SRG observatory started to map the entire sky in X-rays. After the 4-year survey program, it will reach flux limits about 25 times deeper than…
Profile changes associated with DM events in PSR J1713+0747
Fang Xi Lin, Hsiu-Hsien Lin, Jing Luo +5
Propagation effects in the interstellar medium and intrinsic profile changes can cause variability in the timing of pulsars, which limits the accuracy of fundamental science done v…
The Polarized Image of a Synchrotron Emitting Ring of Gas Orbiting a Black Hole
Ramesh Narayan, Daniel C. M. Palumbo, Michael D. Johnson +237
Synchrotron radiation from hot gas near a black hole results in a polarized image. The image polarization is determined by effects including the orientation of the magnetic field i…
