2. APOD: 2014 February 24 - The Cloudy Cores of Active Galaxies
... 2014 February 24 . The Cloudy Cores of Active Galaxies . Image Credit: NASA's GSFC , W. Steffen ( UNAM ) . Explanation: What would it look like to travel to the center of an active galaxy? Most galactic centers are thought to house black hole s millions of times more massive than our Sun. The spaces surrounding these supermassive black holes may be far from dormant, however, flickering in many colors and earning the entire object class the title of Active Galactic Nuclei (AGN). ...

5. New LBV Star Discovered in the Galaxy
... Luminous blue variable (LBV) stars are the most massive stars with 40-120 solar masses, which are passing the short stage of evolution losing their hydrogen envelopes before exploding as Supernovae. These are extremely rare objects, only about a dozen of the most massive LBVs are known in the Galaxy. ... In the spectral observations of stars with infrared circular nebulae, found in the Spitzer survey (24 microns), a new LBV star in the Galaxy was discovered. It was named MN112. ...

10. Massive galaxies discovered in the early Universe | ESO
... Science User Portal . ... Galaxies . ... ESOтАЩs VISTA survey telescope has spied a horde of previously hidden massive galaxies that existed when the Universe was in its infancy. By discovering and studying more of these galaxies than ever before, astronomers have for the first time found out exactly when such monster galaxies first appeared. A few of the newly discovered massive galaxies are shown in close-up on these small subsets of the UltraVISTA field. ... Early Universe : Galaxy . ...

12. Hubble Provides Multiple Views of How to Feed a Black Hole (PRC98-14)
... Astronomers have used NASA's Hubble Space Telescope to probe the core of the nearest active galaxy to Earth, Centaurus A. Hubble's Near Infrared Camera and Multi-Object Spectrometer was used to peer past the dust to discover a tilted disk of hot gas at the galaxy's center (white bar running diagonally across image center). This 130 light-year diameter disk encircles a suspected black hole which may be one billion times the mass of our Sun. ... Centaurus A (NGC 5128) Fast Facts . ...

A new class of objects has been discovered - the Ultraluminous X-ray (ULX) sources, which could be as black holes of intermediate mass (100-1000 suns), being captured by galaxies and spiralling in because of dynamical friction, or microquasars (SS433-like stars), being orientated "face-on". ...

15. Search for distant radio galaxies in SAO
... The search for distant objects which can be both galaxies and quasars is one of the most important problems of observational astrphysics, because it allows one to determine cosmological parameters connected with the time of appearence and evolution of stellar systems, large scale structure of the Universe. ... Radio galaxies are important objects to be studied because they are sources of infrared-optical-ultraviolet continuum, emission lines and continual radio emission. ...

17. (S-7a) The Black Hole at the Center of our Galaxy
... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...
