VLBA observations of a sample of low-power compact symmetric objects
M. Orienti, F. D'Ammando, D. Dallacasa +3
Compact symmetric objects (CSOs) are intrinsically compact extragalactic radio sources that are thought to be the progenitors of classical radio galaxies. To date, evolutionary mod…
A high-resolution radio morphology and polarization of the kpc-scale X-ray jet of PKS 1127-145
M. Orienti, A. Siemiginowska, F. D'Ammando +1
We report on new multi-frequency Very Large Array (VLA) radio observations and Chandra X-ray observations of a radio-loud quasar with a ~300 kpc long jet, PKS 1127-145, during a fl…
Investigating X-ray Emission in the GeV-emitting Compact Symmetric Objects PKS 1718-649 and TXS 1146+596
E. Bronzini, G. Migliori, C. Vignali +8
Compact Symmetric Objects (CSOs) are thought to represent the first step in the evolutionary path of radio galaxies. In this work, we investigate the X-ray emission of two CSOs con…
Roaring to softly whispering: Persistent X-ray emission at the location of the Fast Blue Optical Transient AT2018cow 3.7 yrs after discovery and implications on accretion-powered scenarios
G. Migliori, R. Margutti, B. D. Metzger +11
We present the first deep X-ray observations of a luminous FBOT AT2018cow, at since discovery, together with the re-analysis of the observation at d…
The extremely X-ray luminous radio-loud quasar CFHQS J142952+544717 at under Chandra high-angular resolution lens
G. Migliori, A. Siemiginowska, M. Sobolewska +6
We present the first X-ray observation at sub-arcsecond resolution of the high-redshift () radio-loud quasar CFHQS J142952+544717 (J1429). The ~100 net-count 0.3-7 keV spec…
Unprecedented X-ray Emission from the Fast Blue Optical Transient AT2022tsd
D. J. Matthews, R. Margutti, B. D. Metzger +8
We present the X-ray monitoring campaign of AT2022tsd in the time range d rest-frame since discovery. With an initial 0.3-10 keV X-ray luminosity of $L_x \ap…
Young but fading radio sources: searching for remnants among compact steep-spectrum radio sources
M. Orienti, M. Murgia, D. Dallacasa +2
The incidence of young but fading radio sources provides important information on the life cycle of radio emission in radio-loud active galactic nuclei. Despite its importance for…
The Fourth Catalog of Active Galactic Nuclei Detected by the Fermi Large Area Telescope -- Data Release 3
LAT collaboration, Marco Ajello, Luca Baldini +100
An incremental version of the fourth catalog of active galactic nuclei (AGNs) detected by the Fermi-Large Area Telescope is presented. This version (4LAC-DR3) derives from the thir…
Multi-scale VLBI observations of the candidate host galaxy of GRB 200716C
S. Giarratana, M. Giroletti, C. Spingola +3
We present the discovery and the subsequent follow up of radio emission from SDSS J130402.36293840.6 (J1304+2938), the candidate host galaxy of the gamma-ray burst GRB~200716C.…
The Fourth Catalog of Active Galactic Nuclei Detected by the Fermi Large Area Telescope -- Data Release 2
B. Lott, D. Gasparrini, S. Ciprini
An incremental version (4LAC-DR2) of the fourth catalog of active galactic nuclei (AGNs) detected by the Fermi-LAT is presented. This version is associated with the second release…
The Fourth Catalog of Active Galactic Nuclei Detected by the Fermi Large Area Telescope
LAT collaboration
The fourth catalog of active galactic nuclei (AGNs) detected by the Fermi Gamma-ray Space Telescope Large Area Telescope (4LAC) between 2008 August 4 and 2016 August 2 contains 286…
X-rays from the location of the Bactrian Transient ASASSN-15lh
R. Margutti, B. D. Metzger, R. Chornock +13
We present the detection of persistent soft X-ray radiation with L_x ~ 10^41-10^42 erg/s at the location of the extremely luminous, double-humped transient ASASSN-15lh as revealed…
