Resolving the temporal evolution of M87 jet with -arcsec Chandra observations
Camille Poitras, Gerrit Schellenberger, Ralph Kraft +3
We present a 13-year Chandra/HRC-I study of the M87 jet, using point-spread-function deconvolution to achieve unprecedented sub-arcsecond X-ray resolution of its kiloparsec-scale s…
A Faint Progenitor System for the Faint Supernova 2024vjm
Erez A. Zimmerman, Avishay Gal-Yam, Paul J. Groot +68
Type Ia Supernovae (SNe Ia) are well known for their role as standardizable cosmological candles. Their uniformity is credited to their single origin as thermonuclear explosions of…
Milli-arcsec X-ray positions and X-ray varstrometry for the strongly lensed AGN HE 0435-1223
Alysa Rogers, Daniel Schwartz, Cristiana Spingola +1
Active galactic nuclei (AGN) are some of the most powerful objects in the Universe. For this reason, they can be observed up to high redshifts (z), giving valuable insights into th…
A Near Magnetic-to-kinetic Energy Equipartition Flare from the Relativistic Jet in AO 0235+164 during 2013-2019
Whee Yeon Cheong, Sang-Sung Lee, Sang-Hyun Kim +17
We present the multiwavelength flaring activity of the blazar AO 0235+164 during its recent active period from 2013 to 2019. From a discrete correlation function (DCF) analysis, we…
Unravelling the complex behavior of Mrk 421 with simultaneous X-ray and VHE observations during an extreme flaring activity in April 2013
MAGIC collaboration, V. A. Acciari, S. Ansoldi +237
We report on a multi-band variability and correlation study of the TeV blazar Mrk 421 during an exceptional flaring activity observed from 2013 April 11 to 2013 April 19. The study…
VERITAS Detection of LS 5039 and HESS J1825-137
VERITAS Collaboration, A. U. Abeysekara, W. Benbow +42
With 8 hours of observations, VERITAS confirms the detection of two very high energy gamma-ray sources. The gamma-ray binary LS 5039 is detected with a statistical significance of…
