DESI-253.2534+26.8843: A New Einstein Cross Spectroscopically Confirmed with VLT/MUSE and Modeled with GIGA-Lens
Aleksandar Cikota, Ivonne Toro Bertolla, Xiaosheng Huang +10
Gravitational lensing provides unique insights into astrophysics and cosmology, including the determination of galaxy mass profiles and constraining cosmological parameters. We pre…
The polarized signal from broad emmission lines in AGN
P. Lira, R. W. Goosmann, M. Kishimoto +1
Using the STOKES Monte Carlo radiative transfer code we revisit the predictions of the spectropolarimetric signal from a disc-like Broad Emission Line Region (BLR) in Type I AGN du…
The QUEST-La Silla AGN Variability Survey: selection of AGN candidates through optical variability
P. Sánchez-Sáez, P. Lira, R. Cartier +6
We used data from the QUEST-La Silla Active Galactic Nuclei (AGN) variability survey to construct light curves for 208,583 sources over deg, with a a limiting magnitu…
Nebular H Limits for Fast Declining Type Ia Supernovae
D. J. Sand, R. C. Amaro, M. Moe +16
One clear observational prediction of the single degenerate progenitor scenario as the origin of type Ia supernovae (SNe) is the presence of relatively narrow (1000 km s$^…
The QUEST-La Silla AGN variability survey: connection between AGN variability and black hole physical properties
P. Sánchez-Sáez, P. Lira, J. Mejía-Restrepo +5
We present our statistical analysis of the connection between active galactic nuclei (AGN) variability and physical properties of the central supermassive black hole (SMBH). We con…
Nebular Spectroscopy of the `Blue Bump' Type Ia Supernova 2017cbv
D. J. Sand, M. L. Graham, J. Botyánszki +17
We present nebular phase optical and near-infrared spectroscopy of the Type Ia supernova (SN) 2017cbv. The early light curves of SN~2017cbv showed a prominent blue bump in the ,…
Near Infrared Variability of obscured and unobscured X-ray selected AGN in the COSMOS field
P. Sánchez, P. Lira, R. Cartier +9
We present our statistical study of near infrared (NIR) variability of X-ray selected Active Galactic Nuclei (AGN) in the COSMOS field, using UltraVISTA data. This is the largest s…
The QUEST-La Silla AGN Variability Survey
Régis Cartier, Paulina Lira, Paolo Coppi +7
We present the characterization and initial results from the QUEST-La Silla AGN variability survey. This is an effort to obtain well sampled optical light curves in extragalactic f…
