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…
Line shapes in narrow-line Seyfert 1 galaxies: a tracer of physical properties?
M. Berton, I. Björklund, A. Lähteenmäki +4
Line profiles can provide fundamental information on the physics of active galactic nuclei (AGN). In the case of narrow-line Seyfert 1 galaxies (NLS1s) this is of particular import…
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…
A luminous stellar outburst during a long-lasting eruptive phase first, and then SN IIn 2018cnf
A. Pastorello, A. Reguitti, A. Morales-Garoffolo +45
We present the results of the monitoring campaign of the Type IIn supernova (SN) 2018cnf (aka ASASSN-18mr). It was discovered about 10 days before the maximum light (on MJD = 58293…
Luminous Red Novae: Stellar Mergers or Giant Eruptions?
A. Pastorello, E. Mason, S. Taubenberger +36
We present extensive datasets for a class of intermediate-luminosity optical transients known as "luminous red novae" (LRNe). They show double-peaked light curves, with an initial…
