Star formation in self-gravitating disks in active galactic nuclei. I. Metallicity gradients in broad line regions
Star formation self-gravitating disks active galactic Metallicity gradients
2011/10/11
It has been suggested that the high metallicity generally observed in active galactic nuclei (AGNs) and quasars originates from ongoing star formation in the self-gravitating part of accretion disks a...
Can a Satellite Galaxy Merger Explain the Active Past of the Galactic Center?
Satellite Galaxy Merger Explain Active Past Galactic Center
2011/10/9
Observations of the Galactic Center (GC) have accumulated a multitude of "forensic" evidence indicating that several million years ago the center of the Milky Way galaxy was teaming with starforming a...
Feeding and feedback in the active nucleus of Mrk 1157 probed with Gemini NIFS
galaxies: individual (Mrk 1157) – galaxies: individual (NGC591) – galaxies:Seyfert – galaxies: ISM – infrared: galaxies – galaxies: kinematics and dynamics
2011/10/8
We have mapped the stellar and gaseous kinematics, as well as the emission-line flux distributions and ratios, from the inner 450pc radius of Mrk1157, using 2D near-IR spectra obtained with the Gemini...

QSO Pairs across Active Galaxies: Evidence of Blueshifts?
Quasars: emission lines quasars: absorption lines cosmology: miscellaneous
2009/5/7
Several QSO pairs have been reported and their redshifts determined, where the two objects in each pair are located across an active galaxy. The usually accepted explanation of such occurrences is tha...
MONITORING ACTIVE STARS 29 DRA,12 CAM AND COLOUR EXCESS OF II PEG
Stars late type-starspots-Stars individual 29 Dra, 12 Cam, II Peg
2009/2/11
We present the BV light curves analysis of late-type, long-period
stars 29 Dra, 12 Cam for the season 2005/2006, and shorter-period star II Peg for
the same season. High latitude spots (alternativel...
Influence of the Black Hole Rotation on Accretion Discs and Jets in Active Galaxies: the Case of NGC 1068
the Black Hole Rotation Accretion Discs and Jets Active Galaxies the Case of NGC 1068
2010/10/18
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...
