The ESA's Planck satellite, dedicated to studying the early Universe and its subsequent evolution, was launched 14 May 2009 has been scanning microwave submillimetre sky continuously since 12 August 2009. This paper gives an overview of mission performance, processing, analysis, characteristics data, scientific results, science data products papers in release. include maps CMB diffuse extragalactic foregrounds, a catalogue compact Galactic sources, list sources detected through SZ effect....
We present the all-sky Planck catalogue of Sunyaev-Zeldovich (SZ) sources detected from 29 month full-mission data. The (PSZ2) is largest SZ-selected sample galaxy clusters yet produced and deepest clusters. It contains 1653 detections, which 1203 are confirmed with identified counterparts in external data-sets, first cluster survey containing > $10^3$ a detailed analysis selection function terms its completeness statistical reliability, placing lower limit 83% on purity.

The European Space Agency's Planck satellite, dedicated to studying the early Universe and its subsequent evolution, was launched 14~May 2009 scanned microwave submillimetre sky continuously between 12~August 23~October 2013. In February~2015, ESA Collaboration released second set of cosmology products based on data from entire mission, including both temperature polarization, along with a scientific technical papers web-based explanatory supplement. This paper gives an overview main...
Chandra observations of large samples galaxy clusters detected in X-rays by ROSAT provide a new, robust determination the cluster mass functions at low and high redshifts. Statistical systematic errors are now sufficiently small, redshift leverage for function evolution to be used as useful growth structure-based dark energy probe. In this paper, we present cosmological parameter constraints obtained from 37 with 〈z〉 = 0.55 derived 400 deg2 serendipitous survey 49 brightest z ≈ 0.05 All-Sky...
We discuss the measurements of galaxy cluster mass functions at z ≈ 0.05 and 0.5 using high-quality Chandra observations samples derived from ROSAT PSPC All-Sky 400 deg2 surveys. provide a full reference for data analysis procedures, present updated calibration relations between total its X-ray indicators (TX, Mgas, YX) based on subsample low-z relaxed clusters, first measurement evolving LX–Mtot relation (with Mtot estimated obtained well defined statistically complete sample with...
We present constraints on cosmological parameters using number counts as a function of redshift for sub-sample 189 galaxy clusters from the Planck SZ (PSZ) catalogue. The PSZ is selected through signature Sunyaev--Zeldovich (SZ) effect, and used here has signal-to-noise threshold seven, with each object confirmed cluster all but one estimate. discuss completeness sample our construction likelihood analysis. Using relation between mass $M$ signal $Y$ calibrated to X-ray measurements, we...
We describe the all-sky Planck catalogue of clusters and cluster candidates derived from Sunyaev--Zeldovich (SZ) effect detections using first 15.5 months satellite observations. The contains 1227 entries, making it over six times size Early SZ (ESZ) sample largest SZ-selected to date. It 861 confirmed clusters, which 178 have been as mostly through follow-up observations, a further 683 are previously-known clusters. remaining 366 status candidates, we divide them into three classes...
We have gathered optical photometry data from the literature on a large sample of Swift-era gamma-ray burst (GRB) afterglows including GRBs up to September 2009, for total 76 GRBs, and present an additional three pre-Swift not included in earlier sample. Furthermore, we publish 840 new points 42 GRB afterglows, sets 050319, 050408, 050802, 050820A, 050922C, 060418, 080413A 080810. analyzed light curves all derived spectral energy distributions with best quality, allowing us estimate host...
Taking advantage of the all-sky coverage and broadfrequency range Planck satellite, we study Sunyaev-Zeldovich (SZ) pressure profiles 62 nearby massive clusters detected at high significance in 14-month nominal survey. Careful reconstruction SZ signal indicates that most are individually least out to R500. By stacking radial profiles, have statistically 3 × R500, i.e., a density contrast about 50–100, though dispersion mean profile dominates statistical errors across whole range. Our...
The orbital observatory Spectrum-Roentgen-Gamma (SRG), equipped with the grazing-incidence X-ray telescopes Mikhail Pavlinsky ART-XC and eROSITA, was launched by Roscosmos to Lagrange L2 point of Sun–Earth system on July 13, 2019. launch carried out from Baikonur Cosmodrome a Proton-M rocket DM-03 upper stage. German telescope eROSITA installed SRG under an agreement between Roskosmos DLR, Aerospace Agency. In December 2019, started perform its main scientific task: scanning celestial sphere...
Astronomical Roentgen Telescope – X-ray Concentrator (ART-XC) is the hard instrument with grazing incidence imaging optics on board Spektr-Roentgen-Gamma (SRG) observatory. The SRG observatory flagship astrophysical mission of Russian Federal Space Program, which was successively launched into orbit around second Lagrangian point (L2) Earth-Sun system a Proton rocket from Baikonur cosmodrome 13 July 2019. ART-XC telescope will provide first ever true all-sky survey performed in 4–30 keV...
We present the first sample of tidal disruption events (TDEs) discovered during SRG all-sky survey. These 13 were selected among X-ray transients detected in 0<l<180 deg hemisphere by eROSITA its second sky survey (10 June - 14 December 2020) and confirmed optical follow-up observations. The most distant event occurred at z=0.581. One TDE continued to brighten least 6 months. spectra are consistent with nearly critical accretion onto black holes a few 10^3 10^8 M_Sun, although supercritical...
We present a catalog of galaxy clusters detected in new ROSAT PSPC survey. The survey is optimized to sample, at high redshifts, the mass range corresponding T> keV z=0. Technically, our extension 160 square degrees (Vikhlinin etal 98a, Mullis 2003). use same detection algorithm, thus preserving quality resulting sample; main difference significant increase sky coverage. covers 397 and based on 1610 Galactic latitude pointings, virtually all pointed data suitable for distant clusters....
We present the scaling relation between Sunyaev-Zeldovich (SZ) signal and stellar mass for almost 260,000 locally brightest galaxies (LBGs) selected from Sloan Digital Sky Survey (SDSS). These are predominantly central of their dark matter halos. calibrate stellar-to-halo conversion using realistic mock catalogues based on Millennium Simulation. Applying a multi-frequency matched filter to Planck data each LBG, averaging results in bins mass, we measure mean SZ down $M_\ast\sim 2\times...

We examine the relation between galaxy cluster mass M and Sunyaev-Zeldovich (SZ) effect signal for a sample of 19 objects which weak lensing (WL) measurements obtained from Subaru Telescope data are available in literature. Hydrostatic X-ray masses derived XMM-Newton archive data, SZ is measured Planck all-sky survey data. find an that consistent slope normalisation with previous determinations using masses; however, there offset respect to measures based on hydrostatic mass-proxy relations....
