    Optical photometry of two transitional millisecond pulsars in the radio pulsar state
    We present ULTRACAM multiband optical photometry of two transitional millisecond pulsars (tMSPs), PSR J1023+0038 and PSR J1227-4853, taken while both were in...
  • Publication
    Optical polarization and spectral properties of the hydrogen-poor superluminous supernovae SN 2021bnw and SN 2021fpl
    New optical photometric, spectroscopic, and imaging polarimetry data are combined with publicly available data to study some of the physical properties of the...

    Optical spectral characterization of the gamma-ray blazars S4 0954+65, TXS 1515-273, and RX J0812.0+0237
    The study of gamma-ray blazars is usually hindered due to the lack of information on their redshifts and on their low-energy photon fields. This information is...

    Optical spectral characterization of the TeV extreme blazar 2WHSP J073326.7+515354
    The emission from the relativistic jets in blazars usually outshines their host galaxies, challenging the determination of their distances and the...

    Optical spectroscopy of Arp220: the star formation history of the closest ULIRG
    We present long-slit, optical spectra of the merging system Arp220, obtained using the William Herschel Telescope (WHT) on La Palma. These data were taken as a...

    Optical spectroscopy of BL Lac objects: TeV candidates
    We investigate the spectroscopic optical properties of gamma-ray sources detected with high significance above 50 GeV in the Third Catalog of Hard Fermi-LAT...

    Optical spectroscopy of blazars for the Cherenkov Telescope Array - II
    Active galactic nuclei (AGNs) make up about 35 per cent of the more than 250 sources detected in very high-energy (VHE) gamma rays to date with the imaging...
