MID-INFRARED SPECTROSCOPY OF CANDIDATE ACTIVE GALACTIC NUCLEI-DOMINATED SUBMILLIMETER GALAXIES
starburst submillimeter
font style='font-size:12px;'>
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
font style='font-size:12px;'>
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...
Reconstruction of f(R, T) gravity describing matter dominated and accelerated phases
Reconstruction gravity describing dominated accelerated phases

2011/10/12
We investigate the cosmological reconstruction in modified f(R,T) gravity, where R is the Ricci scalar and T the trace of the stress-energy tensor. Special attention is attached to the case in which t...
Central free-free-dominated 880 $\micron$ emission in II Zw 40

2011/10/20
The central star-forming region in a blue compact dwarf galaxy, II Zw 40, was observed in the 340 GHz ($880 \micron$) band at $\sim 5$ arcsec (250 pc) resolution with the Submillimetre Array (SMA). A ...
The Kelvin-Helmholtz instability in weakly ionised plasmas: Ambipolar dominated and Hall dominated flows
mhd – instabilities – ISM:clouds – ISM:kinematics and dynamics
font style='font-size:12px;'>
2011/10/12
The Kelvin-Helmholtz instability is well known to be capable of converting well-ordered flows into more disordered, even turbulent, flows. As such it could represent a path by which the energy in, for...

2011/9/27
In this paper we extend the range of consistency of a constant bulk viscosity model to redshifts up to $z\sim 8.1$. In this model the dark sector of the cosmic substratum is a viscous fluid with press...

On the Relativistic Beaming and Orientation Effects in Core-Dominated Quasars

font style='font-size:12px;'>
2009/5/19
In this paper, we investigate the relativistic beaming effects
in a well-defined sample of core-dominated quasars using the correlation
between the relative prominence of the core with respect to th...
