Aims. With the purpose of producing first detailed full view Puppis A in X-rays, we carried out new XMM-Newton observations covering missing regions southern half supernova remnant (SNR) and combined them with existing Chandra data.
We report on an optical (SDSS) and X-ray (XMM) study of optically selected sample four dual AGN systems at projected separations 30--60~kpc. All sources are detected in the band (0.3-10 keV); seven objects identified as Seyfert, while one source, classified a LINER, is likely powered by accretion virtue its relatively high luminosity (1.2$\times10^{41}$ erg/s). Six eight obscured X-rays with N$_{\rm H} \geq$ 10$^{23}$ cm$^{-2}$; three these, whose spectrum dominated reflection component,...
Context. The identification of counterparts dark gamma-ray sources adds greatly to our understanding their underlying astrophysical processes.
We report the discovery of active star formation in H I cloud associated with interacting Seyfert system NGC 3227/3226 that was originally identified as a candidate tidal dwarf galaxy (TDG) by Mundell et al. and we name J1023+1952. present broadband optical B, R, (from Isaac Newton Telescope), ultraviolet images XMM-Newton) show is massive ongoing seen cluster blue knots (MB ≲ -15.5 mag) surrounded diffuse halo cospatial ridge high neutral hydrogen column density (NH ~ 3.7 × 1021 cm-2)...
We have observed the Arp 270 system (NGC 3395 & NGC 3396) in H{\alpha} emission using GH{\alpha}FaS Fabry-Perot spectrometer on 4.2m William Herschel Telescope (La Palma). In 3396, which is edge-on to us, we detect gas inflow towards centre, and also axially confined opposed outflows, characteristic of galactic superwinds, go examine possibility that there a shrouded AGN nucleus. The combination surface brightness, velocity dispersion information enabled us measure radii, FWHM, masses 108...
We present a multiwavelength study of newly discovered compact group (CG), SDSS J0959+1259, based data from XMM–Newton, Sloan Digital Sky Survey (SDSS) and the Calar Alto optical imager BUSCA. With maximum velocity offset 500 km s−1, mean redshift 0.035, spatial extension 480 kpc, this CG is exceptional in having highest concentration nuclear activity local Universe, established with sensitivity limit LX > 4 × 1040 erg s−1 2–10 keV band R-band magnitude MR < −19.

While theory and simulations indicate that galaxy mergers play an important role in the cosmological evolution of accreting black holes their host galaxies, samples Active Galactic Nuclei (AGN) galaxies at close separations are still small. In order to increase sample AGN pairs, we undertook archival project investigate X-ray properties a SDSS-selected 32 pairs with $\le$150 kpc containing one optically-identified AGN, were serendipitously observed by XMM-Newton. We discovered only...
We report on XMM-Newton observations of three nearby galaxy pairs, AM0707-273, AM1211-465, and AM2040-674. All six galaxies were previously classified as HII based optical IR spectroscopic analysis. detected with each member was isolated analyzed independently. The X-ray spectra reveal strong evidence AGN activity in the NE AM1211-465 pair. measured a luminosity 1042 erg/s 2–10 keV band presence neutral FeKα line confidence level 98.8%. high value, 2.2 ± 0.21022 cm-2, would explain...
ABSTRACT Star formation accretion on to the super massive black holes (SMBHs) and feedback processes link evolution of galaxies with their SMBHs. X-ray observations in imaging spectral regime have revealed be an important tool study connection between nuclear activity circumnuclear star nearby active galactic nuclei (AGN). diagnostics can lead disentangle, which is ionization mechanism central kiloparsecs AGN.

Abstract We assessed the scientific productivity of XMM‐ Newton by examining publications and data usage statistics. analyse 3272 refereed papers, published until end 2012, that directly use data. The SAO/NASA Astrophysics Data System (ADS) was used to provide additional information on each paper including number citations. For paper, observation identifiers instruments results were determined. access XMM‐Newton Science Archive (XSA) detailed observations themselves original proposals....
In this paper we present an overview of the MAGNA (Multiple AGN Activity) project aiming at a comprehensive study multiple super‐massive black hole systems.
