With future space exploration in mind, a Cornell-led team of astronomers has published the final maps of Titan’s liquid methane rivers and tributaries – as seen by NASA’s late Cassini mission – so tha...
An AzTEC 1.1 mm survey of the GOODS-N field - I. Maps, catalogue and source statistics
detectors sub-millimetre
2014/12/23
We have conducted a deep and uniform 1.1 mm survey of the Great Observatories Origins Deep Survey-North (GOODS-N) field with AzTEC on the James Clerk Maxwell Telescope. Here, we present the first resu...
PACS and SPIRE photometer maps of M 33: First results of the HERschel M 33 Extended Survey (HERM33ES)
M 33 Simple isothermal
2014/12/22
Context. Within the framework of the HERM33ES key program, we are studying the star forming interstellar medium in the nearby, metal-poor spiral galaxy M 33, exploiting the high resolution and s...
AzTEC half square degree survey of the SHADES fields - I. Maps, catalogues and source counts
hydrodynamical models galaxy formation
2014/12/20
We present the first results from the largest deep extragalactic mm-wavelength survey undertaken to date. These results are derived from maps covering over 0.7 deg2, made at λ= 1.1 mm, using the AzTEC...

Reddening and metallicity maps of the Milky Way Bulge from VVV and 2MASS. I.The method and minor axis maps
Galaxy: bulge - ISM: dust, extinction - stars: abundances
2011/10/18
We present a method to obtain reddening maps and to trace structure and metallicity gradients of the bulge using data from the recently started ESO public survey Vista Variables in the Via Lactea (VVV...
2MASS wide field extinction maps: IV. The Orion, Mon R2, Rosette, and Canis Major star forming regions
clouds dust extinction structure individual objects Orion molecular complex
2011/10/21
We present a near-infrared extinction map of a large region (approximately 2200 deg^2) covering the Orion, the Monoceros R2, the Rosette, and the Canis Major molecular clouds. We used robust and optim...
The Optical Gravitational Lensing Experiment. OGLE-III Photometric Maps of the Galactic Bulge Fields
Optical Gravitational Lensing Experiment OGLE-III Photometric Galactic Bulge Fields
2011/10/12
We present OGLE-III Photometric Maps of the Galactic bulge fields observed during the third phase of the OGLE project. This paper describes the last, concluding set of maps based on OGLE-III data.
Th...
In the context of the geometrical analysis of weakly non Gaussian CMB maps, the 2D differential extrema counts as functions of the excursion set threshold is derived from the full moments expansion of...
The deeply obscured AGN of NGC4945 I. Spitzer-IRS maps of [Ne V], [Ne II], H2 0-0 S(1), S(2), and other tracers
Galaxies:active – Galaxies:nuclei – Galaxies:individual:NGC 4945 – ISM:lines and bands
2011/9/27
The nearly edge-on galaxy NGC4945 is one of the closest galaxies where an AGN and starburst coexist, and is one of the brightest sources at 100 keV. Near and mid-infrared spectroscopy have shown very ...
Deep Near-Infrared Survey of the Pipe Nebula II: Data, Methods, and Dust Extinction Maps
ISM clouds – infrared ISM –stars formation
2010/11/11
We present a new set of high resolution dust extinction maps of the nearby and essentially
starless Pipe Nebula molecular cloud. The maps were constructed from a concerted deep nearinfrared imaging s...
