We present the observations of the starburst galaxy M82 taken with the Herschel SPIRE Fourier-transform spectrometer. The spectrum (194-671 μm) shows a prominent CO rotational ladder from J = 4-3 to 13-12 emitted by the central region of M82. The fundamental properties of the gas are well constrained by the high J lines observed for the first time

The background that will be observed by IXO's X-ray detectors naturally separates into two components: (1) a Cosmic X-ray Background (CXB), primarily due to unresolved point sources at high energies (E>2 keV), along with Galactic component(s) at lower energies that are generated in the disk and halo as well as the Local Bubble and charge exchange

Context. The present work deals with the detection of phase changes in an exoplanetary system. HD 46375 is a solar analog known to host a non-transiting Saturn-mass exoplanet with a 3.0236 day period. It was observed by the CoRoT satellite for 34 days during the fall of 2008. Aims: We attempt to identify at optical wavelengths, the changing phases

This article presents a toolkit for defining simple but powerful systems. PORIS toolkit is an open and extensible source collaborative project that allows describing system graph-based systems and their behavior in a snapshot. It provides a web editor for a domain visual specific language (DSL) and transformation tools to generate software

The observations were carried out using the five-channel photopolarimeter of the Torino Astronomical Observatory attached to the 2.15m telescope at the Complejo Astronomico El Leoncito (CASLEO; Argentina). They were performed over eight nights (June 27-30, 2006 and June 15-18, 2007). (1 data file).

Aims: We exploit the deepest existing far-infrared (FIR) data obtained so far by Herschel at 100 and 160 μm in the GOODS-N, as part of the PACS evolutionary probe (PEP) survey, to derive for the first time the evolution of the rest-frame 60-μm, 90-μm, and total IR luminosity functions (LFs) of galaxies and AGNs from z = 0 to unprecedented high
