DETAILED DECOMPOSITION OF GALAXY IMAGES. II. BEYOND AXISYMMETRIC MODELS
We present a two-dimensional (2D) fitting algorithm (GALFIT, ver. 3) with new capabilities to study the structural components of galaxies and other astronomical objects in digital images. Our… Expand
The eleventh and twelfth data releases of the Sloan Digital Sky Survey: final data from SDSS-III
- S. Alam, F. D. Albareti, +725 authors Key Laboratory of Optical Astronomy
- Physics, Geology
- 5 January 2015
The third generation of the Sloan Digital Sky Survey (SDSS-III) took data from 2008 to 2014 using the original SDSS wide-field imager, the original and an upgraded multi-object fiber-fed optical… Expand
MAMBO Mapping Of Spitzer c2d Small Clouds And Cores
- J. Kauffmann, F. Bertoldi, +10 authors S. Institute
- Physics
- 27 May 2008
Aims. To study the structure of nearby (<500 pc) dense starless and star-forming cores with the particular goal to identify and understand evolutionary trends in core properties, and to explore the… Expand
The statistics of lambda CDM Halo Concentrations
- A. F. Neto, Liang Gao, +19 authors H Germany
- Physics
- 20 June 2007
We use the Millennium Simulation (MS) to study the statistics of Λ cold dark matter (ΛCDM) halo concentrations at z= 0. Our results confirm that the average halo concentration declines monotonically… Expand
A Method of Correcting Near‐Infrared Spectra for Telluric Absorption*
- W. Vacca, M. Cushing, John T. Rayner IfA, U. Hawaii, Mpe, H Germany
- Physics
- 12 November 2002
We present a method for correcting near-infrared medium-resolution spectra for telluric absorption. The method makes use of a spectrum of an A0 V star, observed near in time and close in air mass to… Expand
alpha-, r-, and s-process element trends in the Galactic thin and thick disks
- T. Bensby, S. Feltzing, +9 authors H Germany
- Physics
- 6 December 2004
From a detailed elemental abundance analysis of 102 F and G dwarf starswe present abundance trends in the Galactic thin and thick disks for 14elements (O, Na, Mg, Al, Si, Ca, Ti, Cr, Fe, Ni, Zn, Y,… Expand
PMAS : The potsdam multi-aperture spectrophotometer. I. Design, manufacture, and performance
We describe the design, manufacture, commissioning, and performance of PMAS, the Potsdam Multi-Aperture Spectrophotometer. PMAS is a dedicated integral field spectrophotometer optimized to cover the… Expand
The structural and scaling properties of nearby galaxy clusters. II. The M-T relation
- M. Arnaud, E. Pointecouteau, G. W. P. S. D. CEA-Saclay, F. M. Garching, H Germany
- Physics
- 10 February 2005
Using a sample of ten nearby ($z\lesssim 0.15$), relaxed galaxy clusters in the temperature range [2–9]$~\rm keV$, we have investigated the scaling relation between the mass at various density… Expand
Offline Handwriting Recognition with Multidimensional Recurrent Neural Networks
Offline handwriting recognition—the automatic transcription of images of handwritten text—is a challenging task that combines computer vision with sequence learning. In most systems the two elements… Expand

Systematic Molecular Differentiation in Starless Cores
- M. Tafalla, P. Myers, +9 authors H Germany
- Physics
- 20 December 2001
We present evidence that low-mass starless cores, the simplest units of star formation, are systematically differentiated in their chemical composition. Some molecules, including CO and CS, almost… Expand
