The NAture of the Faint Far-Infrared Extragalactic Source Population: Optical/NIR and Radio Follow-Up Observationts of ISOPHOT Deep-Field Sources using the Keck, Subaru, and VLA Telescopes.
Keck Subaru
2014/12/26
In order to search for obscured objects at high redshifts, we have made deep far-infrared (FIR) deep survey in the Lockman Hole using ISOPHOT onboard ISO (Kawara et al. 1998, A&A, 336, L9). In this su...
An infrared imaging survey of the faint Chandra sources near the Galactic Centre
stars mass loss
2014/12/24
We present near-infrared imaging of a sample of the faint, hard X-ray sources discovered in the 2001 Chandra Advanced CCD Imaging Spectrometer (ACIS)-I survey towards the Galactic Centre (GC) by Wang ...
THE HUBBLE SPACE TELESCOPE WIDE FIELD CAMERA 3 EARLY RELEASE SCIENCE DATA: PANCHROMATIC FAINT OBJECT COUNTS FROM 0.2{2 MICRONS WAVELENGTH
Galactic stars counts the galaxy counts
2014/12/22
We describe the Hubble Space Telescope (HST) Wide Field Camera 3 (WFC3) Early Re- lease Science (ERS) observations in the Great Observatories Origins Deep Survey (GOODS) South eld. The new WFC3 ERS d...
Faint Extended OH Emission from the Local Interstellar Medium in the Direction l \approx 108\circ, b \approx 5\circ
OH Emission Local Interstellar Medium Cosmology and Extragalactic Astrophysics
2012/2/21
We have mapped faint 1667 OH line emission (TA \approx 20 - 40 mK in our \approx 30' beam) along many lines of sight in the Galaxy covering an area of \approx 4\circ \times 4\circ in the general direc...
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...
Far-infrared and Molecular CO Emission From the Host Galaxies of Faint Quasars at z~6
Far-infrared Molecular CO Emission Host Galaxies Faint Quasars
2011/10/21
We present new millimeter and radio observations of nine z~6 quasars discovered in deep optical and near-infrared surveys. We observed the 250 GHz continuum in eight of the nine objects and detected t...
Flux density measurements of a complete sample of faint blazars
fl ux density spectral index polarisation – galaxies quasars BL Lacs radio continuum galaxies
2011/10/18
We performed observations with the Effelsberg 100-m radio telescope to measure flux densities and polarised emission of sources selected from the "Deep X-ray Radio Blazar Survey" (DXRBS) to better def...
The Faint End of the Luminosity Function and Low Surface Brightness Galaxies
Luminosity Function Low Surface Brightness Galaxies
2011/10/9
SHELS (Smithsonian Hectospec Lensing Survey) is a dense redshift survey covering a 4 square degree region to a limiting R = 20.6. In the construction of the galaxy catalog and in the acquisition of sp...
Sparse aperture masking at the VLT I. Faint companion detection limits for the two debris disk stars HD 92945 and HD 141569
Instrumentation: high angular resolution – Stars: planetary systems – Stars: individual
2011/9/29
Observational data on companion statistics around young stellar systems is needed to flesh out the formation pathways for extrasolar planets and brown dwarfs. Aperture masking is a new technique that ...
