Planck Intermediate Results. XI: The gas content of dark matter halos: the Sunyaev-Zeldovich-stellar mass relation for locally brightest galaxies

Planck Collaboration, P. A. R. Ade, N. Aghanim +194

We present the scaling relation between Sunyaev-Zeldovich (SZ) signal and stellar mass for almost 260,000 locally brightest galaxies (LBGs) selected from the Sloan Digital Sky Surv…

The dust SED of dwarf galaxies I. The case of NGC 4214

Israel Hermelo, Ute Lisenfeld, Monica Relaño +3

The goal of the present study is to establish the physical origin of dust heating and emission based on radiation transfer models, which self-consistently connect the emission comp…

CALIFA, the Calar Alto Legacy Integral Field Area survey. II. First public data release

CALIFA collaboration, B. Husemann, K. Jahnke +74

We present the first public data release of the CALIFA survey. It consists of science-grade optical datacubes for the first 100 of eventually 600 nearby (0.005<z<0.03) galaxies, ob…

Modulation of the waterfall by a gauge field

David H. Lyth, Mindaugas Karciauskas

We present the first complete calculation of the curvature perturbation generated during the hybrid inflation waterfall, caused by the coupling of the waterfall field to a gauge fi…

Chemical abundances in M31 from HII regions

Almudena Zurita, Fabio Bresolin

We have obtained multi-slit spectroscopic observations from 3700A to 9200A with LRIS at the Keck I telescope for 31 HII regions in the disk of the Andromeda galaxy (M31), spanning…

HI asymmetry in the isolated galaxy CIG 85 (UGC 1547)

C. Sengupta, T. C. Scott, L. Verdes Montenegro +10

We present the results from the Giant Metrewave Radio Telescope (GMRT) interferometric HI and 20 cm radio continuum observations of CIG 85, an isolated asymmetric galaxy from the A…
