The dependence of mass and environment on the secular processes of AGNs in terms of morphology, colour, and specific star-formation rate
(2018)
Context. Galaxy mass and environment play a major role in the evolution of galaxies. In the transition from star-forming to quenched galaxies, active galactic nuclei (AGNs) also have a principal action therein. However, ...
Tracing kinematic (mis)alignments in CALIFA merging galaxies: Stellar and ionized gas kinematic orientations at every merger stage
(EDP Sciences, 2015-10)
We present spatially resolved stellar and/or ionized gas kinematic properties for a sample of 103 interacting galaxies, tracing all merger stages: close companions, pairs with morphological signatures of interaction, and ...
A 3-D perspective to the internal properties of low and high-redshift galaxies
(2019)
In the present work, I study the morpho-kinematics of two moderate galaxy samples at
low- and high-redshift. I analyse the internal kinematics of these galaxies aiming to find
possible correlations between the kinematic ...
PGC 0029664-1188757: Photometry of Two Interacting Galaxies and Their Debris
(2010)
We present basic data on the stellar populations of the interacting galaxies PGC0029664 and PGC1188757, and their debris. Comparing B, V, R, and I deep photometry and colors obtained with the Magellan telescope with models ...
Double starbursts triggered by mergers in hierarchical clustering scenarios
(Oxford University Press, 2002-06)
We use cosmological smooth particle hydrodynamical (SPH) simulations to study the effects of mergers in the star formation history of galactic objects in hierarchical clustering scenarios. We find that during some merger ...
Sistemas peculiares de galaxias :
(2009-03)
Se presenta un estudio estadístico sobre grupos compactos y fósiles identificados en simulaciones numéricas combinadas
con diferentes modelos semianalíticos de formación de galaxias. Los resultados fueron también confrontados ...
Analysis of interacting and isolated quasars
(EDP Sciences, 2018-07)
The main goal of this study was to determine the effects on equivalent widths (EWs) of some spectral lines produced in the quasars by the presence of surrounding galaxies. To carry this out, a sample of 4663 quasars (QSOs) ...
On the effect of chaotic orbits on dynamical friction
(IOP Publishing, 2001-12)
Chaotic orbits suffer significant changes as a result of small perturbations. One can thus wonder whether the dynamical friction suffered by a satellite on a regular orbit, and interacting with the stars of a galaxy, will ...
A unified solution to the small scale problems of the Lambda CDM model II: introducing parent-satellite interaction
(Iop Publishing Ltd, 2014-12-01)
We continue the study of the impact of baryon physics on the small scale problems of the Lambda CDM model, based on a semi-analytical model (Del Popolo, 2009). With such model, we show how the cusp/core, missing satellite ...
NGC 6845 Revisited: Stellar Kinematics on the Early Type Member Galaxies
(IOP Publishing, 2021-07)
We observed the compact group of galaxies NGC 6845 with GMOS-S imaging and long-slit spectroscopy. The group itself is comprised of two spiral galaxies and two S0 galaxies, and shows signs of gravitational interaction among ...
