AT 2016blu: Accretion-Powered Outbursts in a Luminous Blue Variable and Compact Object Binary
Mojgan Aghakhanloo, Núria Torres-Albà, Nathan Smith +33
We present the first X-ray detection of the supernova (SN) impostor AT 2016blu in NGC 4559. AT 2016blu exhibited 27 detected quasiperiodic (~113 day) outbursts between 2012 and Jun…
Profile Analysis of the Multiwavelength 2.1-year Oscillations of PG 1553+113
P. Peñil, P. Peñil, N. Torres-Albà +8
We investigate the morphology of the oscillation profiles of the blazar PG~1553+113 in relation to its well-known 2.1 yr periodicity. We identify individual cycles in the …
X-ray Absorption Variability in NGC 1142: Another Constraint on the Nature of the Torus/Broad-Line Region in Active Galactic Nuclei
Isaiah S. Cox, Núria Torres-AlbÃ, Stefano Marchesi +5
The paper analyzes nine X‑ray observations of the active galaxy NGC 1142 over ~20 years to study changes in line‑of‑sight column density, using torus models to infer the geometry a…
The hidden variability of the torus in local Active Galactic Nuclei: 20 years of Chandra, XMM-Newton, and NuSTAR observations
Vittoria Elvezia Gianolli, Nuria Torres-Alba, Stefano Marchesi +9
X-ray absorption variability in active galactic nuclei (AGN) provides key constraints on the structure and dynamics of the circumnuclear obscuring medium, the so-called torus. A fr…
The Multi-phase Biconical Outflow in the local IR-Luminous Merger IRASF01364-1042
Y. Song, V. U, J. Kader +37
We investigate the spatially-resolved ISM properties of the local (), IR-luminous (\,L), late-stage galaxy merger IRAS F01364-1042, comb…
SAPLE: Swift Analysis Pipeline for Lightcurve Extraction
Lea Marcotulli, Núria Torres-AlbÃ
We present the Swift Analysis Pipeline for Lightcurve Extraction (SAPLE), a semi-automated pipeline to extract the Swift-UVOT and Swift-XRT data products and spectral information (…
