We report a study of the relation between dust and gas over a 100 deg2 area in the Taurus molecular cloud. We compare the H2 column density derived from dust extinction with the CO column density deri...
COLOR-MAGNITUDE RELATION AND MORPHOLOGY OF LOW-REDSHIFT ULIRGs IN SLOAN DIGITAL SKY SURVEY
color-magnitude morphological analysis
2014/12/20
We present color-magnitude and morphological analysis of 54 low-redshift ultraluminous infrared galaxies (ULIRGs; 0.018 < z < 0.265 with z median = 0.151), a subset of the Infrared Astronomical Satell...
Investigating the break in the Cepheid period-luminosity relation and its implications
Cepheid variable stars Cycle luminosity Linear time. universal
2014/12/9
The Cepheid period-luminosity (PL) relation is a major component in the distance scale ladder. This relation has been considered to be linear (within period ranges of ～2 to ～100 days) and universal (i...
Merger induced scatter and bias in the cluster mass - Sunyaev-Zeldovich effect scaling relation
cosmology: large-scale structure of Universe, galaxies: clusters: general, meth- ods: N-body simulations
2011/10/20
We examine sources of scatter in scaling relations between galaxy cluster mass and thermal Sunyaev-Zeldovich (SZ) effect using cluster samples extracted from cosmological hydrodynamical simulations. O...
GRB091127/SN2009nz and the VLT/X-shooter spectroscopy of its host galaxy: probing the faint end of the mass-metallicity relation
Gamma-rays bursts: individual: GRB091127 – supernovae: individual: SN2009nz – Galaxies: ISM– Galaxies: evolution
2011/10/12
We perform a detailed study of the gamma-ray burst GRB091127/SN2009nz host galaxy at z=0.490 using the VLT/X-shooter spectrograph in slit and integral-field unit (IFU). From the analysis of the optica...
The intrinsic dispersion of the Faber-Jackson relation for early-type galaxies as function of the mass and redshift
Galaxies fundamental parameters photometry distances redshifts
2011/10/18
Aims. Recently it has been reported that the intrinsic dispersion at constant magnitude of the structural relations from early-type galaxies is a useful tool to study the universality of these structu...

BH-galaxy relation AGN Narrow Seyfert Galaxies
2011/10/12
Massive black holes (BHs) are detected in the centers of many nearby galaxies are linearly correlated with the luminosity of the host bulge (spheroid), the black hole mass being about 0.1% of the stel...
Galaxy-galaxy lensing constraints on the relation between baryons and dark matter in galaxies in the Red Sequence Cluster Survey 2
gravitational lensing: weak - galaxies: formation - galaxies: halos
2011/10/12
We present the results of a study of weak gravitational lensing by galaxies using imaging data that were obtained as part of the second Red Sequence Cluster Survey (RCS2). In order to compare to the b...
The Baryonic Tully-Fisher Relation of Gas Rich Galaxies as a Test of LCDM and MOND
Baryonic Tully-Fisher Relation Rich Galaxies LCDM MOND
2011/10/9
The Baryonic Tully-Fisher Relation (BTFR) is an empirical relation between baryonic mass and rotation velocity in disk galaxies. It provides tests of galaxy formation models in LCDM and of alternative...
