Broadband X-ray observations of four gamma-ray narrow-line Seyfert 1 galaxies
M. Berton, V. Braito, S. Mathur +4
Narrow-line Seyfert 1 galaxies (NLS1s) is one of the few classes of active galactic nuclei (AGN) harboring powerful relativistic jets and detected in rays. NLS1s are well-known…
A correlation between [O III] line property and X-ray spectral complexity in narrow-line Seyfert 1 galaxies?
S. Chen, G. La Mura, M. Berton +7
We present a detailed study of 11 narrow-line Seyfert 1 galaxies (NLS1s) from the Six-degree Field Galaxy Survey (6dFGS) that both have optical and X-ray spectroscopic observations…
Fermi and Swift Observations of GRB 190114C: Tracing the Evolution of High-Energy Emission from Prompt to Afterglow
M. Ajello, M. Arimoto, M. Axelsson +147
We report on the observations of gamma-ray burst (GRB) 190114C by the Fermi Gamma-ray Space Telescope and the Neil Gehrels Swift Observatory. The early-time observations reveal mul…
SN 2017gmr: An energetic Type II-P supernova with asymmetries
Jennifer E. Andrews, D. J. Sand, S. Valenti +77
We present high-cadence ultraviolet (UV), optical, and near-infrared (NIR) data on the luminous Type II-P supernova SN 2017gmr from hours after discovery through the first 180 days…
