  • ELAIS optical ident. at 15um & 1.4GHz

    We present the multi-wavelength properties and catalogue of the 15{mu}m and 1.4GHz radio sources detected in the European Large Area ISO Survey (ELAIS) areas N1 and N2. Using...
  • XMM view of NGC 6231: OB stars

    In this second paper of the series, we focus on the X-ray properties of the OB star population of NGC 6231. As a tool for our analysis, we performed a literature-based census of...
  • Radio sources in the 6dFGS

    We have identified 7824 radio sources from the 1.4GHz NRAO VLA Sky Survey (NVSS, Cat. ) with galaxies brighter than K=12.75mag in the Second Incremental Data Release of the 6...
  • LMC point source classification in SAGE-Spec

    We present the classification of 197 point sources observed with the Infrared Spectrograph in the SAGE-Spec Legacy programme on the Spitzer Space Telescope. We introduce a...
  • Lockman Hole North 3GHz catalogue

    This is the second of two papers describing the observations and source catalogues derived from sensitive $3$-GHz images of the Lockman Hole North using the Karl G. Jansky Very...
  • Supernova remnants in M33: X-ray properties

    We have carried out a study of the X-ray properties of the supernova remnant (SNR) population in M33 with XMM-Newton, comprising deep observations of eight fields in M33...
  • X-ray properties of DES-Y1 galaxy clusters

    Using archival X-ray observations and a lognormal population model, we estimate constraints on the intrinsic scatter in halo mass at fixed optical richness for a galaxy cluster...
  • The 2BIGB gamma-ray blazars catalog

    This paper presents the results of a {gamma}-ray likelihood analysis over all the extreme and high synchrotron peak blazars (EHSP and HSP) from the 3HSP catalogue. We...
  • WISE properties of AGNs from the AT20G survey

    Past studies of compact active galactic nuclei (AGNs), the dominant population at high radio frequencies, selected them using flat spectral index criteria. This biases the...
  • SCUBA-2-COSMOS field brightest sub-mm sources

    We present an ALMA study of the ~180 brightest sources in the SCUBA-2 850-{mu}m map of the COSMOS field from the S2COSMOS survey, as a pilot study for AS2COSMOS - a full survey...
  • New radio catalogue for M83 SNR and HII regions

    We present a new catalogue of radio sources in the face-on spiral galaxy M83. Radio observations taken in 2011, 2015, and 2017 with the Australia Telescope Compact Array at 5.5...
  • NuSTAR Extragalactic Surveys, NEP Field

    We present the NuSTAR extragalactic survey of the James Webb Space Telescope (JWST) North Ecliptic Pole (NEP) Time-Domain Field. The survey covers a ~0.16deg^2^ area with a...
  • H-ATLAS DR3 NIR counterparts in SGP field

    In this paper, we present the third data release (DR3) of the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS). We identify likely near- infrared counterparts to...
  • PS1 edge-on Galaxies catalog

    We present a catalogue of 16551 edge-on galaxies created using the public DR2 data of the Pan-STARRS survey. The catalogue covers the three quarters of the sky above Dec. =...
  • Low-mass cool dwarfs of NYMGs from Gaia EDR3

    Gaia EDR3 offers greatly improved kinematics for nearby objects, including members of nearby young stellar moving groups (NYMGs). In this study, we aim to identify low-mass NYMG...
  • Study of highly variable XMMSL2 sources

    We present the identifications of a flux-limited sample of highly variable X-ray sources on long time-scales from the second catalogue of the XMM-Newton SLew survey (XMMSL2)....
  • NVSS and FIRST variable sources

    In the present study we have cross-correlated NVSS and FIRST radio catalogues having radio flux measurements at the same 1.4GHz frequency. This way we benefit from repeated...
  • Activity types of ROSAT/SDSS galaxies

    In this study we carry out detailed spectral classification of 173 AGN candidates from the Joint HRC/BHRC sample, which is a combination of HRC (Hamburg-ROSAT Catalogue) and...
  • Catalog of X-ray active galactic nuclei

    A general catalog of active galactic nuclei (AGN) has been created from identified optical sources of X-ray data from the Hamburg-ROSAT Catalog (HRC) and the Byurakan-Hamburg...
  • AGN selected from an HRC/BHRC sample. II.

    This is a detailed spectral classification of 198 candidate active galactic nuclei (AGN) from a joint HRC/BHRC sample consisting of a combination of the HRC (Hamburg-ROSAT) and...
