Radio and Far-Infrared Emission as Tracers of Star Formation and Active Galactic Nuclei in Nearby Cluster Galaxies
AWM7 A426
2014/12/24
We have studied the radio and far-infrared (FIR) emission from 114 galaxies in the seven nearest clusters (<100 Mpc) with prominent X-ray emission to investigate the impact of the cluster environment ...
MID-INFRARED SPECTROSCOPY OF CANDIDATE ACTIVE GALACTIC NUCLEI-DOMINATED SUBMILLIMETER GALAXIES
starburst submillimeter
2014/12/23
We report the detection of CO molecular line emission in the z = 4.5 millimeter-detected galaxy COSMOS J100054+023436 (hereafter J1000+0234) using the IRAM Plateau de Bure interferometer (PdBI) and NR...
MID-INFRARED SPECTROSCOPY OF CANDIDATE ACTIVE GALACTIC NUCLEI-DOMINATED SUBMILLIMETER GALAXIES
Spitzer spectroscopy evolutionary sequence
2014/12/20
Spitzer spectroscopy has revealed that 80% of submm galaxies (SMGs) are starburst (SB)-dominated in the mid-infrared. Here we focus on the remaining 20% that show signs of harboring powerful active ga...

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...
The long-term millimeter activity of active galactic nuclei
Galaxies: active — Quasars: general — Radiation mechanisms: non-thermal
2011/10/18
We analyze the long-term evolution of the fluxes of six active galactic nuclei (AGN) - 0923+392, 3C 111, 3C 273, 3C 345, 3C 454.3, and 3C 84 - in the frequency range 80-267 GHz using archival calibrat...
Dual-Frequency Observations of 140 Compact, Flat-Spectrum Active Galactic Nuclei for Scintillation-Induced Variability
Flat-Spectrum Active Galactic Nuclei Variability
2011/10/8
The 4.9 GHz Micro-Arcsecond Scintillation-Induced Variability (MASIV) Survey detected a drop in Interstellar Scintillation (ISS) for sources at redshifts z > 2, indicating an apparent increase in angu...

PROGRESS REPORT ON THE MONITORING ACTIVE LATE-TYPE STARS IN 2005/2006 AND THE ANALYSIS OF V523 CAS
Stars late type-Stars activity-starspots-Stars individual V523 Cas
2009/2/18
We present the light curve analysis of late-type binary V523 Cas
for the season 2005. The spot has been revealed on the secondary. According to
theoretical considerations, the spot appeared to be ho...
QSO Pairs across Active Galaxies: Evidence of Blueshifts?
Quasars emission lines—quasars absorption lines—cosmology miscellaneous
2010/9/16
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...
