Rubin LSST DP2 unveils almost-dark galaxies in the Virgo Cluster
Minh Ngoc Le, Johan H. Knapen, Željko Ivezić +27
Galaxies with the faintest surface brightness are currently known only in the Local Group. Similar objects should exist beyond our vicinity and are crucial for understanding galaxy…
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…
SDSS-IV MaNGA: The Incidence of Major Mergers in type I and II AGN Host Galaxies in the DR15 sample
Héctor Hernández-Toledo, Edgar Cortes-Suárez, Jose Antonio Vázquez-Mata +4
We present a study on the incidence of major mergers and their impact on the triggering of nuclear activity in 47 type I and 236 type II optically-selected AGN from the MaNGA DR15…
SDSS-IV MaNGA: Identification and Multiwavelength Properties of Type-1 AGN in the DR15 sample
Edgar Cortes-Suárez, C. Alenka Negrete, Héctor M. Hernández-Toledo +2
We present a method to identify type-1 active galactic nuclei (AGN) in the central 3 arcsec integrated spectra of galaxies in the MaNGA DR15 sample. It is based on flux ratios esti…
Preparing for low surface brightness science with the Vera C. Rubin Observatory: characterisation of tidal features from mock images
G. Martin, A. E. Bazkiaei, M. Spavone +50
Tidal features in the outskirts of galaxies yield unique information about their past interactions and are a key prediction of the hierarchical structure formation paradigm. The Ve…
The differences between mass- and light-derived structural parameters over time for MaNGA Elliptical galaxies
H. Ibarra-Medel, V. Avila-Reese, I. Lacerna +4
We apply stellar population synthesis analysis to obtain spatially-resolved archaeological inferences for a large sample of "red and dead" Elliptical galaxies (Classical Elliptical…
The - and -to-stellar mass correlations of late- and early-type galaxies and their consistency with the observational mass functions
A. R. Calette, Vladimir Avila-Reese, Aldo Rodríguez-Puebla +2
We compile and carrefully homogenize local galaxy samples with available information on stellar, and/or masses, and morphology. After processing the informatio…
SDSS IV MaNGA: The global and local stellar mass assemby histories of galaxies
Héctor J. Ibarra-Medel, Sebastián F. Sánchez, Vladimir Avila-Reese +10
By means of the fossil record method implemented through Pipe3D, we reconstruct the global and radial stellar mass growth histories (MGHs) of an unprecedentedly large sample of gal…
The Bulgeless Seyfert/LINER Galaxy NGC 3367: Disk, Bar, Lopsidedness and Environment
H. M. Hernández-Toledo, M. Cano-Díaz, O. Valenzuela +4
NGC3367 is a nearby isolated active galaxy that shows a radio jet, a strong bar and evidence of lopsidedness. We present a quantitative analysis of the stellar and gaseous structur…
The Synoptic All-Sky Infrared (SASIR) Survey
Joshua S. Bloom, J. Xavier Prochaska, William Lee +42
We are proposing to conduct a multicolor, synoptic infrared (IR) imaging survey of the Northern sky with a new, dedicated 6.5-meter telescope at San Pedro Mártir (SPM) Observatory.…
