A Molecular Line Scan in the Hubble Deep Field North: Constraints on the CO Luminosity Function and the Cosmic H2 Density
F. Walter, R. Decarli, M. Sargent +19
We present direct constraints on the CO luminosity function at high redshift and the resulting cosmic evolution of the molecular gas density, (z), based on a blind mole…
A molecular line scan in the Hubble Deep Field North
R. Decarli, F. Walter, C. Carilli +20
We present a molecular line scan in the Hubble Deep Field North (HDF-N) that covers the entire 3mm window (79-115 GHz) using the IRAM Plateau de Bure Interferometer. Our CO redshif…
The Atlas3D project -- XXVII. Cold Gas and the Colours and Ages of Early-type Galaxies
L. M. Young, N. Scott, P. Serra +22
We present a study of the cold gas contents of the Atlas3D early-type galaxies, in the context of their optical colours, near-UV colours, and Hβ absorption line strengths. Early-ty…
Investigating the hard X-ray emission from the hottest Abell cluster A2163 with Suzaku
N. Ota, K. Nagayoshi, G. W. Pratt +3
We present the results from Suzaku observations of the hottest Abell galaxy cluster A2163 at . To study the physics of gas heating in cluster mergers, we investigated hard X…
Measurement of acoustic glitches in solar-type stars from oscillation frequencies observed by Kepler
A. Mazumdar, M. J. P. F. G. Monteiro, J. Ballot +15
For the very best and brightest asteroseismic solar-type targets observed by Kepler, the frequency precision is sufficient to determine the acoustic depths of the surface convectiv…
The NIKA instrument: results and perspectives towards a permanent KID based camera for the Pico Veleta observatory
A. D'Addabbo, R. Adam, A. Adane +32
The New IRAM KIDs Array (NIKA) is a pathfinder instrument devoted to millimetric astronomy. In 2009 it was the first multiplexed KID camera on the sky; currently it is installed at…
