Spatially-Resolved Spectroscopy of SDSS J0952+2552: a Confirmed Dual AGN
Spectroscopy SDSS J0952+2552: Confirmed Dual AGN
2011/10/9
Most massive galaxies contain supermassive black holes (SMBHs) in their cores. When galaxies merge, gas is driven to nuclear regions and can accrete onto the central black hole. Thus one expects to se...
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...
The quasar SDSS J142507.32+323137.4 : dual AGNs?
galaxies active — galaxies individual (SDSS J142507.32+323137.4) —quasars emission lines
2010/11/16
We analyze the optical spectrum of type 1 QSO SDSS J1425+3231. This object is interesting since its narrow emission lines such as [O III]4959, 5007 are doublepeaked,and the line structure can be mod...
Post-Decadal White Paper: A Dual-Satellite Dark-Energy/Microlensing NASA-ESA Mission

A confluence of scientific, financial, and political factors imply that launching two simpler, more narrowly defined dark-energy/microlensing satellites will lead to faster, cheaper, better (and more ...
