  • RASS-MCMF catalog

    We present the RASS-MCMF catalogue of 8449 X-ray selected galaxy clusters over 25000deg^2^ of extragalactic sky. The accumulation of deep multiband optical imaging data, the...
  • Galaxy surveys in quasars fields

    We present a study of metal-enriched halo gas traced by Mg II and C IV absorption at z < 2 in the MUSE Analysis of Gas around Galaxies survey and the Quasar Sightline and...
  • Galaxy clusters redshifts with VLT/MUSE

    We present strong-lensing analyses of three galaxy clusters, RX J2129.4 + 0009 (z = 0.235), MS 0451.6 - 0305 (z = 0.55), and MACS J2129.4 - 0741 (z = 0.589), using the powerful...
  • The bTFr of MIGHTEE-H I spiral galaxies

    Using a sample of 67 galaxies from the MeerKAT International GigaHertz Tiered Extragalactic Exploration Survey Early Science data, we study the H I-based baryonic Tully-Fisher...
  • PAHs bands in starburst-dominated galaxies

    Polycyclic aromatic hydrocarbons (PAHs) are of great astrochemical and astrobiological interest due to their potential to form prebiotic molecules. We analyse the 7.7 and...
  • UV luminosity functions of SFR galaxies

    We use ultraviolet (UV) imaging taken with the XMM-Newton Optical Monitor telescope (XMM-OM), covering 280 arcmin^2^ in the UVW1 band ({lambda}eff = 2910 {AA}) to measure...
  • Thermal parameters of the IGM at 2 <= z <= 4

    We characterize the thermal state of the intergalactic medium (IGM) in 10 redshift bins in the range 2 <= z <= 4 with a sample of 103 high-resolution, high S/N Ly{alpha}...
  • Kinematic study of KGES galaxies

    We present the KMOS Galaxy Evolution Survey (KGES), a K-band Multi-Object Spectrograph (KMOS) study of the H_{alpha} and [N II] emission from 288 K-band- selected galaxies at...
  • Study of relativistic jets in blazar objets

    Our understanding of the unification of jetted AGN has evolved greatly as jet samples have increased in size. Here, based on the largest-ever sample of over 2000 well-sampled...
  • Properties and X-rays of RLQs and RQQs quasars

    We present X-ray spectral and long-term variability analyses of an unbiased sample of 361 optically selected radio-loud quasars (RLQs) utilizing sensitive serendipitous X-ray...
  • High-z H-II star-forming galaxies

    We present independent determinations of cosmological parameters using the distance estimator based on the established correlation between the Balmer line luminosity,...
  • X-ray properties of 26 high-luminosity quasars

    We present an investigation of the interdependence of the optical-to-X-ray spectral slope (aox), the HeII equivalent-width (EW), and the monochromatic luminosity at 2500{AA}...
  • Lya-UV Offsets in Galaxies at z~6

    We study the projected spatial offset between the ultraviolet continuum and Lya emission for 65 lensed and unlensed galaxies in the Epoch of Reionization 5<=z<=7, the...
  • A Chandra survey of z >= 4.5 quasars

    X-ray observations provide a unique probe of the accretion disc corona of supermassive black holes (SMBHs). In this paper, we present a uniform Chandra X-ray data analysis of a...
  • Core-collapses supernovae host galaxies

    We present a comprehensive study of an unbiased sample of 150 nearby (median redshift, z = 0.014) core-collapse supernova (CCSN) host galaxies drawn from the All-Sky Automated...
  • Survey for z< 0.04 CLAGNs

    We have conducted a systematic survey for z<0.04 active Galactic nuclei (AGNs) that may have changed spectral class over the past decade. We use SkyMapper, Pan-STARRS and the...
  • Census of circumgalactic MgII at redshift z=<0.5

    This paper presents a survey of MgII absorbing gas in the vicinity of 380 random galaxies, using 156 background quasi-stellar objects (QSOs) as absorption-line probes. The...
  • Sub-damped Lyman {alpha} systems in XQ-100 II

    We present the measured gas-phase metal column densities in 155 sub-damped Ly {alpha} systems (subDLAs) with the aim to investigate the contribution of subDLAs to the chemical...
  • ALMA/NOEMA high-z star-forming galaxies

    We have used ALMA and NOEMA to study the molecular gas reservoirs in 61 ALMA-identified submillimetre galaxies (SMGs) in the COSMOS, UDS, and ECDFS fields. We detect ^12^CO...
