Asymmetries in spatially unresolved 21-cm emission line profiles of isolated galaxies
Aditya Manuwal, H. M. Hernández-Toledo, J. A. Vázquez-Mata +4
The origin of asymmetry in the of galaxies remains an elusive problem, largely due to the difficulties associated with distinguishing between its se…
Spectral Evolution and Transient Broad-Line Features in the Isolated AGN UNAM-KIAS 613
Edgar Cortes-Suárez, Paola Marziani, Héctor Manuel Hernández-Toledo +2
We present multi-epoch optical spectroscopy of the isolated elliptical galaxy UNAM-KIAS 613, hosting a low-luminosity Type 1 AGN. Analysis of archival Sloan Digital Sky Survey (SDS…
Morphological Classification of Galaxies Through Structural and Star Formation Parameters Using Machine Learning
G. Aguilar-Argüello, G. Fuentes-Pineda, H. M. Hernández-Toledo +9
We employ the XGBoost machine learning (ML) method for the morphological classification of galaxies into two (early-type, late-type) and five (E, S0--S0a, Sa--Sb, Sbc--Scd, Sd--Irr…
An iterative method to deblend AGN-Host contributions for Integral Field spectroscopic observations
Héctor Ibarra-Medel, Castalia Alenka Negrete, Ivan Lacerna +3
We present a new iterative deblending method to separate the host galaxy (HG) and their Active Galactic Nuclei (AGN) emission with the use of Integral Field spectroscopic (IFS) dat…
The Lockman--SpReSO project. Main properties of infrared selected star-forming galaxies
Mauro González-Otero, Jordi Cepa, Carmen P. Padilla-Torres +18
Methods.We applied distinct selection criteria to attain an SFG sample with minimal AGN contamination. Multiple approaches were used to estimate the intrinsic extinction, SFR and g…
