Context. We present the second Gaia data release, DR2, consisting of astrometry, photometry, radial velocities, and information on astrophysical parameters variability, for sources brighter than magnitude 21. In addition epoch astrometry photometry are provided a modest sample minor planets in solar system. Aims. A summary contents DR2 is presented, accompanied by discussion differences with respect to DR1 an overview main limitations which still survey. Recommendations made responsible use...
Gaia is a cornerstone mission in the science programme of EuropeanSpace Agency (ESA). The spacecraft construction was approved 2006, following study which original interferometric concept changed to direct-imaging approach. Both and payload were built by European industry. involvement scientific community focusses on data processing for international Data Processing Analysis Consortium (DPAC) selected 2007. launched 19 December 2013 arrived at its operating point, second Lagrange point...

Context. Gaia Data Release 2 provides high-precision astrometry and three-band photometry for about 1.3 billion sources over the full sky. The precision, accuracy, homogeneity of both are unprecedented. Aims. We highlight power DR2 in studying many fine structures Hertzsprung-Russell diagram (HRD). allows us to present different HRDs, depending particular on stellar population selections. do not aim here completeness terms types stars or evolutionary aspects. Instead, we have chosen several...
The Herschel Multi-tiered Extragalactic Survey (HerMES) is a legacy programme designed to map set of nested fields totalling ∼380 deg2. Fields range in size from 0.01 ∼20 deg2, using the Herschel-Spectral and Photometric Imaging Receiver (SPIRE) (at 250, 350 500 μm) Herschel-Photodetector Array Camera Spectrometer (PACS) 100 160 μm), with an additional wider component 270 deg2 SPIRE alone. These bands cover peak redshifted thermal spectral energy distribution interstellar dust thus capture...
The goal of this paper is to demonstrate the outstanding quality second data release Gaia mission and its power for constraining many different aspects dynamics satellites Milky Way. We focus here on determining proper motions 75 Galactic globular clusters, nine dwarf spheroidal galaxies, one ultra-faint system, Large Small Magellanic Clouds. Using extracted from archive, we derived parallaxes these systems, as well their uncertainties. that errors, statistical systematic, are relatively...
The Herschel ATLAS is the largest open-time key project that will be carried out on Space Observatory. It survey 510 square degrees of extragalactic sky, four times larger than all other surveys combined, in five far-infrared and submillimetre bands. We describe survey, complementary multi-wavelength datasets combined with data, six major science programmes we are undertaking. Using new models based a previous galaxies, present predictions properties sources wavebands.
We exploit the deep and extended far infrared data sets (at 70, 100 160 um) of Herschel GTO PACS Evolutionary Probe (PEP) Survey, in combination with HERschel Multi tiered Extragalactic Survey (HerMES) at 250, 350 500 um, to derive evolution restframe 35 60 90 total (IR) luminosity functions (LFs) up z~4. detect very strong for IR LF combined a density evolution.

Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected based on most stellar evolution models - and also known stellar-origin black holes our Galaxy. It has been proposed those high-mass the remnants massive metal-poor stars. Gaia astrometry is to uncover many Galactic wide-binary systems containing dormant BHs, which may not detected before. The study this will provide...
