XMM-Newton --NuSTAR monitoring campaign of the Seyfert 1 galaxy IC 4329A
A. Tortosa, C. Ricci, E. Shablovinskaia +13
We present the results of a joint {\it XMM-Newton} and {\it NuSTAR} campaign on the active galactic nucleus (AGN) IC 4329A, consisting of 9 20 ks {\it XMM-Newton} observat…
Modeling the Galactic center gamma-ray emission with more realistic cosmic-ray dynamics
Andrés Scherer, Jorge Cuadra, Franz E. Bauer
Very-high-energy gamma-ray observations of the Galactic center (GC) show extended emission that is strongly correlated with the morphology of the central molecular zone (CMZ). The…
GRB Optical and X-ray Plateau Properties Classifier Using Unsupervised Machine Learning
Shubham Bhardwaj, Maria G. Dainotti, Sachin Venkatesh +4
The division of Gamma-ray bursts (GRBs) into different classes, other than the "short" and "long", has been an active field of research. We investigate whether GRBs can be classifi…
BASS-XL: X-ray variability properties of unobscured Active Galactic Nuclei
Alessia Tortosa, Claudio Ricci, Patricia Arévalo +15
We investigate the X-ray variability properties of Seyfert1 Galaxies belonging to the BAT AGN Spectroscopic Survey (BASS). The sample includes 151 unobscured (N c…
Closure Relations of Synchrotron Self-Compton in Afterglow stratified medium and Fermi-LAT Detected Gamma-Ray Bursts
Nissim Fraija, Maria G. Dainotti, B. Betancourt Kamenetskaia +2
The Second Gamma-ray Burst Catalog (2FLGC) was announced by the Fermi Large Area Telescope (Fermi-LAT) Collaboration. It includes 29 bursts with photon energy higher than 10 GeV. G…
Fermi LAT AGN classification using supervised machine learning
Nathaniel Cooper, Maria Giovanna Dainotti, Aditya Narendra +2
Classifying Active Galactic Nuclei (AGN) is a challenge, especially for BL Lac Objects (BLLs), which are identified by their weak emission line spectra. To address the problem of c…
A Tight Correlation Between Millimeter and X-ray Emission in Accreting Massive Black Holes from <100 Milliarcsecond-resolution ALMA Observations
Claudio Ricci, Chin-Shin Chang, Taiki Kawamuro +10
Recent studies have proposed that the nuclear millimeter continuum emission observed in nearby active galactic nuclei (AGN) could be created by the same population of electrons tha…
A fast radio burst localized at detection to an edge-on galaxy using very-long-baseline interferometry
Tomas Cassanelli, Calvin Leung, Pranav Sanghavi +48
Fast radio bursts (FRBs) are millisecond-duration, luminous radio transients of extragalactic origin. These events have been used to trace the baryonic structure of the Universe us…
K2 Optical Emission from OJ 287 and Other Gamma-Ray Blazars on Hours-to-Weeks Timescales from 2014-2018
Ann E. Wehrle, Michael Carini, Paul J. Wiita +5
We present second observations by K2 of OJ~287 and 7 other -ray AGNs obtained in 2017-2018, second and third observations of the lobe-dominated, steep spectrum quasar 3C~207, an…
Particle In Cell Simulations of Mildly Relativistic Outflows in Kilonova Emissions
Mohira Rassel, Patrick Kilian, Vito Aberham +3
The electromagnetic emission from neutron star mergers is comprised of multiple components. Synchrotron emission from the disk-powered jet as well as thermal emission from the merg…
Extragalactic FXT Candidates Discovered by Chandra (2014-2022)
J. Quirola-Vásquez, F. E. Bauer, P. G. Jonker +9
Extragalactic fast X-ray transients (FXTs) are short flashes of X-ray photons of unknown origin that last a few minutes to hours. We extend the search for extragalactic FXTs from Q…
Multiwavelength monitoring of the nucleus in PBC J2333.9-2343: the giant radio galaxy with a blazar-like core
L. Hernández-García, F. Panessa, G. Bruni +12
PBC J2333.9-2343 is a giant radio galaxy at z = 0.047 with a bright central core associated to a blazar nucleus. If the nuclear blazar jet is a new phase of the jet activity, then…
X-ray Unveiling Events in a z~1.6 Active Galactic Nucleus in the 7 Ms Chandra Deep Field-South
Li-Ming Yu, Bin Luo, William N. Brandt +14
We investigate the extreme X-ray variability of a z = 1.608 active galactic nucleus in the 7 Ms Chandra Deep Field-South (XID 403), which showed two significant X-ray brightening e…
SN2017egm: A Helium-rich Superluminous Supernova with Multiple Bumps in the Light Curves
Jiazheng Zhu, Ning Jiang, Subo Dong +28
When discovered, SN~2017egm was the closest (redshift ) hydrogen-poor superluminous supernova (SLSN-I) and a rare case that exploded in a massive and metal-rich galaxy. Thu…
The Fast X-ray Transient XRT 210423 and its Host Galaxy
D. Eappachen, P. G. Jonker, A. J. Levan +8
Fast X-ray Transients (FXTs) are X-ray flares with a duration ranging from a few hundred seconds to a few hours. Possible origins include the tidal disruption of a white dwarf by a…
