The complete census of optically selected AGNs in the Coma Supercluster: the dependence of AGN activity on the local environment

2011/10/11
To investigate the dependence of the occurrence of active galactic nuclei (AGNs) on local galaxy density, we study the nuclear properties of ~5000 galaxies in the Coma Supercluster whose density spans...
The Evolution of Radio Galaxies and X-ray Point Sources in Coma Cluster Progenitors Since z~1.2

2011/9/30
Using Chandra imaging spectroscopy and Very Large Array (VLA) L-band radio maps, we have identified radio sources at P_{1.4GHz} >=5x10^{23} W Hz^{-1} and X-ray point sources (XPSs) at L_{0.3-8keV}>=5x...

We employ spectroscopic and photometric data from SDSS DR7, in a 500 square degree
region, to understand the evolution of dwarf (M+2Coma
supercluster (z = 0.023). We show...
The HST/ACS Coma Cluster Survey III. Structural Parameters of Galaxies using single-Sérsic Fits

2010/12/29
We present a catalogue of structural parameters for 8814 galaxies in the 25 fields of the HST/ACS Coma Treasury Survey. Parameters from S\'ersic fits to the two-dimensional surface brightness distribu...

2010/3/8
We analyse Spitzer MIPS 24micron observations, and SDSS (DR7) optical broadband photometry and spectra, to investigate the star formation (SF) properties of galaxies residing in the Coma supercluster ...
Effect of Coma Aberration on Orbital Angular Momentum Spectrum of Vortex Beams

<
2013/7/3
Spiral spectra of vortex beams with coma aberration are studied. It is shown that the orbital angular momentum(OAM) states of vortex beams with coma aberration are different from those aberration-free...
