Resolving a Candidate Dual Active Galactic Nucleus with ∼100 pc Separation in MCG-03-34-64

The Astrophysical Journal
We report the serendipitous multiwavelength discovery of a candidate dual black hole system with a separation of ∼100 pc, in the gas-rich luminous infrared galaxy MCG-03-34-64 ( z = 0.016).

HI observations of luminous infrared galaxy mergers

, 2000
A total of 19 luminous infrared galaxy mergers, with L_IR~2 10^11 L_sun for H_0=75 km/s/Mpc, have been observed in the HI line at Nancay and four of them were observed at Arecibo as well. Of these 19, ten had not been observed before. Six were clearly detected, one of which for the first time.

MAMMOTH-Subaru. II. Diverse Populations of Circumgalactic Lyα Nebulae at Cosmic Noon

The Astrophysical Journal Supplement Series
Circumgalactic Ly α nebulae are gaseous halos around galaxies exhibiting luminous extended Ly α emission. This work investigates Ly α nebulae from deep imaging of ∼12 deg ^2 sky, targeted by the MAMMOTH-Subaru survey.

Galaxy evolution in the post-merger regime. III -- The triggering of active galactic nuclei peaks immediately after coalescence

The Open Journal of Astrophysics
Galaxy mergers have been shown to trigger AGN in the nearby universe, but the timescale over which this process happens remains unconstrained. The Multi-Model Merger Identifier (MUMMI) machine vision pipeline has been demonstrated to provide reliable ...

WTP 19aalnxx: Discovery of a Bright Mid-infrared Transient in the Emerging Class of Low-luminosity Supernovae Revealed by Delayed Circumstellar Interaction

The Astrophysical Journal
While core-collapse supernovae (SNe) often show early and consistent signs of circumstellar medium (CSM) interaction, some exhibit delayed signatures due to interaction with distant material around the progenitor star.

The mid-infrared emission of local Luminous Infrared Galaxies

, 2006
En este art´ıculo se combinan la sensibilidad de Spitzer y la alta resolucion espacial de T-ReCS en el GeminiSouth para estudiar las propiedades en el infrarrojo (IR) medio de galaxias luminosas infrarrojas (LIRGs) locales (d < 75 Mpc). Las im´agenes de T-ReCS en 8 − 10 µm nos han permitido separar la emision nuclear (formacion estelar y/o AGN) de la ...

Multiwavelength and Environmental Properties of Variability Selected Low-luminosity Active Galactic Nuclei

The Astrophysical Journal
We present the multiwavelength and environmental properties of 37 variability-selected active galactic nuclei (AGNs), including 30 low-luminosity AGNs (LLAGNs), using a high cadence time-domain survey (All-Sky Automated Survey for SuperNovae) from a ...
