Galaxy interactions and star formation /
(2007-05)
In this thesis we analyse samples of galaxies in pairs obtained from the largest galaxy surveys at the present, the Two Degree Galaxy Redshift Survey (2dFGRS) and the Sloan Digital Sky Survey (SDSS). We have constructed ...
Fast-Growing SMBHs in Fast-Growing Galaxies, at high redshifts: the role of Major Mergers as revealed by ALMA
(Osservatorio Astronomico di Padova (INAF), Italy, 2017)
We present a long-term, multi-wavelength project to understand the epoch of fastest growth of the most massive black holes by using a sample of 40 luminous quasars at z similar or equal to 4.8. These quasars have rather ...
Star formation in H I tails: HCG 92, HCG 100 and six interacting systems
(WILEY-BLACKWELLHOBOKEN, 2012)
We present new Gemini spectra of 14 new objects found within the H?i tails of Hickson Compact Groups (HCGs) 92 and 100. Nine of them are Galaxy Evolution Explorer (GALEX) far-ultraviolet (FUV) and near-ultraviolet (NUV) ...
Effects of collisions and interactions on star formation in galaxy pairs in the field
(Asociación Argentina de Astronomía, 2004-05)
By using cosmological simulations, we study the effect of galaxy interactions on star formation activity in low density regions of the local Universe (z < 0.1). To define galaxy pairs we have used the relative separation ...
Non-virialized clusters for detection of dark energy-dark matter interaction
(Oxford Univ Press, 2015-10-11)
The observation of galaxy and gas distributions, as well as cosmological simulations in a Lambda CDM cold dark matter universe, suggests that clusters of galaxies are still accreting mass and are not expected to be in ...
Search for gamma-ray emission from star-forming galaxies with Fermi LAT
(2016-08)
Recent studies have found a positive correlation between the star-formation rate of galaxies and their gamma-ray luminosity. Galaxies with a high star-formation rate are expected to produce a large amount of high-energy ...

Estudios estadísticos en entornos de galaxias /
(2011-03)
En este trabajo de Tesis se presentan los resultados provenientes de análisis estadísticos de galaxias en diferentes medios.
Utilizando información de los redshifts fotométricos obtenidas a través de redes neuronales para ...
