Recent studies have shown that star formation in mergers does not seem to follow the same Schmidt-Kennicutt (KS) relation as in spiral disks, presenting a higher star formation rate (SFR) for a given ...
The softness parameter is based on the relative intensity of several optical emission lines emitted by the gas ionized by young massive star clusters and can be used to derive the equivalent effective...
Case Studies of Interacting QSO Host Galaxies
Star-Forming Galaxies at z - 2:a major science case for the EMIR/GOYA survey on GTC
In this work we expand the previous discussion of the plausibility of hypothesis of origin of the Lyα forest absorption systems in haloes of normal galaxies in connection with the HubbleDeepField ...
A kinematics of a z = 2.81 galaxy toward bright QSO 0528−250, as inferred from the absorption spectroscopy is discussed. There are sufficient arguments for a far-reaching conclusion that we ar...
A particular case of steady state and spherical symmetry - the so- called logarithmic potential introduced as the ¯rst approximation for dark coronae of galaxies - is studied. Both time and ang...
Although we do not observe directly black holes in the Universe, their presence has been inferred in several astrophysical systems, from galactic to extragalactic scales. In this work, we will restric...
