Black Hole Mass Estimation of a Background Quasar in the Vicinity of the cD Galaxy Holm 15A
Emmanuel Ríos-López, Omar López-Cruz, Ana Luisa González-Morán +1
This study analyzes spectra from the central region of the galaxy cluster Abell 85 observed with GTC/OSIRIS, focusing on the cD galaxy Holm 15A and the point-like X-ray source SDSS…
2D Surface Brightness Modelling of Large 2MASS Galaxies I: Photometry and Structural Parameters
Emmanuel Ríos-López, Christopher Añorve, Héctor J. Ibarra-Medel +4
We have studied a sample of 101 bright 2MASS galaxies from the Large Galaxy Atlas (LGA), whose morphologies span from early to late-types. We have generated estimates for structura…
The Average Physical Properties of A-G Stars Derived from uvby-H Strömgren-Crawford Photometry as the Basis for a Spectral-Classification Synthetical Approach
G. Dalle Mese, O. López-Cruz, W. J. Schuster +2
We have revisited and updated the Strömgren colour and colour-index distributions of A, F and early G-type main sequence stars. For this aim, we selected 7054 dwarf stars al…
Secondary Infall in the Seyfert's Sextet: A Plausible Way Out of the Short Crossing Time Paradox
Omar López-Cruz, Héctor Javier Ibarra-Medel, Sebastián F. Sánchez +6
We used integral field spectroscopy from CALIFA DR3 and multiwavelength publicly-available data to investigate the star-formation histories of galaxies in the Seyfert's Sextet (SS,…
Segmented Vortex Telescope and its Tolerance to Diffraction Effects and Primary Aberrations
Juan P. Treviño, Omar López-Cruz, Sabino Chávez-Cerda
We propose the segmented Large Millimeter Telescope (LMT/GTM),as the largest spatial light modulator capable of producing vortex beams of integer topological charge. This observing…
Empirical Calibration of the Physical Parameters of Solar-like stars using uvby-Strömgren Photometry
Giannina Dalle Mese, Omar López-Cruz, William J. Schuster +2
We present an empirical calibration of the physical parameters of A, F and early G-type stars of luminosity class V. We have used a statistical approach based on a sample of about…
Cluster Galaxy Morphologies: The Relationship among Structural Parameters, Activity and the Environment
Christopher Añorve, Omar López-Cruz, Hector Ibarra-Medel +1
We use an approach to estimate galaxy morphologies based on an ellipticity (e) vs. Bulge-to-Total ratio (B/T) plane. We have calibrated this plane by comparing with Dressler's clas…
