  • L1551 IRS 5 and NE jets radio images

    Using observations with e-MERLIN and the VLA, together with archival data from ALMA, we obtain high-resolution radio images of two binary YSOs: L1551 IRS 5 and L1551 NE,...
  • LoTSS-DR2 Source catalog cone search

    In this data release from the ongoing LOw-Frequency ARray (LOFAR) Two-metre Sky Survey (LoTSS) we present 120-168 MHz images covering 27% of the northern sky. Our coverage is...
  • LoTSS-DR2 Gaussian catalog cone search

    In this data release from the ongoing LOw-Frequency ARray (LOFAR) Two-metre Sky Survey (LoTSS) we present 120-168 MHz images covering 27% of the northern sky. Our coverage is...
  • LoTSS-DR2 mosaics

    In this data release from the ongoing LOw-Frequency ARray (LOFAR) Two-metre Sky Survey (LoTSS) we present 120-168 MHz images covering 27% of the northern sky. Our coverage is...
  • Bootes field source catalogue at 400MHz

    The dominant source of radio continuum emissions at low frequencies is synchrotron radiation, which originates from star-forming regions in disc galaxies and from powerful jets...
  • CO emission from 78 WISE HII region in the OSC

    The Outer Scutum-Centaurus arm (OSC) is the most distant molecular spiral arm known in the Milky Way. The OSC may be the very distant end of the well-known Scutum-Centaurus arm,...
  • HII region candidates in the OSC spiral arm

    The Outer Scutum-Centaurus (OSC) spiral arm is the most distant molecular spiral arm in the Milky Way, but until recently little was known about this structure. Discovered by...
  • Swift Master Catalog

    (no description available) Cone search capability for table B/swift/swiftlog (SWIFT logs)
  • Timing the earliest quenching events

    We present a sample of 151 massive (M_*>10^10^M{sun}) quiescent galaxies at 2<z<5, based on a sophisticated Bayesian spectral energy distribution fitting analysis of...
  • K-CLASH: star-forming galaxies at z~0.2-0.6

    We present the KMOS-CLASH (K-CLASH) survey, a K-band Multi-Object Spectrograph (KMOS) survey, of the spatially resolved gas properties and kinematics of 191 (pre-dominantly...
  • Behaviour of the MgII 2798{AA} line in AGNs

    We investigate the responsiveness of the 2798{AA} MgII broad emission line in active galactic nuclei (AGNs) on time-scales of several years. Our study is based on a sample of...
  • L_x_-L_uv_-L_radio_ relation in radio-loud quasars

    Radio-loud quasars (RLQs) are more X-ray luminous than predicted by the X-ray-optical/UV relation (i.e. L_x_{prop.to}L_uv_^{gamma}^) for radio-quiet quasars (RQQs). The excess...
  • Young Supernova Experiment (YSE) DR1

    We present the Young Supernova Experiment Data Release 1 (YSE DR1), comprised of processed multicolor PanSTARRS1 griz and Zwicky Transient Facility (ZTF) gr photometry of 1975...
  • The Ly{alpha} Reference Sample (LARS). XIV.

    We present Ly{alpha} imaging of 45 low-redshift star-forming galaxies observed with the Hubble Space Telescope. The galaxies have been selected to have moderate to high star...
  • Studying Type II supernovae using the DES

    Despite vast improvements in the measurement of the cosmological parameters, the nature of dark energy and an accurate value of the Hubble constant (H_0_) in the Hubble-Lemaitre...
  • Carbon-loud SDSS BOSS type II quasars at z>2

    We study the ultraviolet (UV) emission-line ratios of a sample of 145 type II quasars (QSO2s) from Sloan Digital Sky Survey III Baryon Oscillation Spectroscopic Survey, and...
  • SN host galaxies in the dark energy survey I

    The 5-yr Dark Energy Survey Supernova Programme (DES-SN) is one of the largest and deepest transient surveys to date in terms of volume and number of supernovae. Identifying and...
  • LIGO/Virgo third observing run (O3) public alerts

    Searches for electromagnetic counterparts of gravitational-wave signals have redoubled since the first detection in 2017 of a binary neutron star merger with a gamma-ray burst,...
  • X-ray properties of Carina OB1 association

    X-ray properties of the stellar population in the Carina OB1 association are examined with special emphasis on early-type stars. Their spectral characteristics provide some...
  • Multiwavelength data of IRAS 20050+2720 young SFR

    IRAS 20050+2720 is young star-forming region at a distance of 700pc without apparent high-mass stars. We present results of our multi-wavelength study of IRAS 20050+2720 which...
