CLAS+: A large catalog of Changing-Look AGN candidates selected through S-PLUS narrow-band photometry
L. Nakazono, L. L. Oliveira, R. R. Valença +11
Changing-look active galactic nuclei (CLAGN) exhibit rapid spectral transitions on timescales of months to years, challenging standard AGN unification models and providing unique i…
Galaxy evolution in compact groups - III. Structural analysis of galaxies and dynamical state of non-isolated compact groups
Gissel P. Montaguth, Ana Laura O'Mill, Claudia Mendes de Oliveira +17
Compact Groups (CGs) of galaxies are dense systems where projected separations are comparable to their optical diameters. A subset - non-isolated CGs - are embedded within major st…
The VVVX quest for satellites around the Circinus galaxy
L. D. Baravalle, A. L. O'Mill, M. V. Alonso +10
The Circinus galaxy is the nearest type-2 Seyfert galaxy, which is at a distance of 4.2 Mpc. Its environment is challenging to explore because it is located at low Galactic latitud…
ODIN: Using multiplicity of Lyman-Alpha Emitters to assess star formation activity in dark matter halos
M. Candela Cerdosino, Nelson Padilla, Ana Laura O'Mill +16
We investigate if systems of multiple Lyman-alpha emitters (LAEs) can serve as a proxy for dark matter halo mass, assess how their radiative properties relate to the underlying hal…
Galaxy evolution in compact groups II. Witnessing the influence of major structures in their evolution
Gissel P. Montaguth, Antonela Monachesi, Sergio Torres-Flores +15
Compact groups (CGs) of galaxies are extreme environments for morphological transformations and the cessation of star formation. Though initially considered isolated, it is now rec…
The evolution of low-mass central galaxies in the vicinity of massive structures and its impact on the two-halo conformity
Daniela Palma, Ivan Lacerna, M. Celeste Artale +7
We investigated the population of low-mass central galaxies with Mstar = Msun/h, inhabiting regions near massive groups and clusters of galaxies using the TNG300…
