Close Galactic Encounter Leaves "Nearly Naked" Supermassive Black Hole
Close Galactic Encounter Leaves Nearly Naked Supermassive Black Hole
2016/11/29
Astronomers using the super-sharp radio vision of the National Science Foundation's Very Long Baseline Array (VLBA) have found the shredded remains of a galaxy that passed through a larger galaxy, lea...
The first IRAM/PdBI polarimetric millimeter survey of active galactic nuclei. II. Activity and properties of individual sources
IRAM/PdBI polarimetric millimeter survey properties individual sources
2012/2/21
We present an analysis of the linear polarization of six active galactic nuclei - 0415+379 (3C~111), 0507+179, 0528+134 (OG+134), 0954+658, 1418+546 (OQ+530), and 1637+574 (OS+562). Our targets were m...
Galactic Phase Transition at E_c= 0.11 eV from Rotation Curves of Cored LSB and nonperturbative Dark Matter Mass
Galactic Phase Transition Rotation Curves Cored LSB nonperturbative Dark Matter
2011/10/8
We analyze the a set of seventeen rotation curves of Low Surface Brightness (LSB) galaxies from the The HI Nearby Galaxy Survey (THINGS) with different mass models to study the core structure and to d...
Nature's Most Precise Clocks May Make "Galactic GPS" Possible; Pulsing Pulsars Help in Search for Gravitational Waves
Nature's Most Precise Clocks Galactic GPS Pulsing Pulsars Gravitational Waves
2010/1/11
Radio astronomers have uncovered 17 millisecond pulsars in our galaxy by studying unknown high-energy sources detected by NASA's Fermi Gamma-ray Space Telescope. The astronomers made the discovery in ...

A COMPARSION OF METAL AD LY-&ALPHA：ABSORPTION IN GALACTIC HALOES
galactic astrophysics observational cosmology GALACTIC HALOES
2009/3/26
The metallicity structure of galactic haloes is one of the major
unknowns in modern galactic astrophysics and observational cosmology. Hereby we
outline a very simple method for obtaining at least a...
OBSERVATIONAL DATA ON GALACTIC SUPERNOVA REMNANTS：I. THE SUPERNOVA REMNANTS WITHIN l = 0° - 90°
Catalogs–ISM supernova remnants–Stars neutron
2009/3/11
We have collected all the available data on Galactic supernova
remnants given in the literature. The data on Galactic supernova remnants located
in the Galactic longitude interval l=0◦–90ϊ...
Some Doubts on the Validity of the Foreground Galactic Contribution
Cosmic microwave background—ISM clouds—dust extinction—ISM structure
2010/9/16
The Galactic foreground contamination inCMBRanisotropies,especially from the dust component, is not easily separable from the cosmological or extragalactic component. In this paper, some doubts will b...
