Optical polarization and spectral properties of the H-poor superluminous supernovae SN 2021bnw and SN 2021fpl
F. Poidevin, C. M. B. Omand, Réka Könyves-Tóth +6
New optical photometric, spectrocopic and imaging polarimetry data are combined with publicly available data to study some of the physical properties of the two H-poor superluminou…
Is there a background population of high-albedo objects in geosynchronous orbits around Earth?
Beatriz Villarroel, Enrique Solano, Hichem Guergouri +11
Old, digitized astronomical images taken before the human spacefaring age offer a unique view of the sky devoid of known artificial satellites. In this paper, we have carried out t…
Post maximum light and late time optical imaging polarimetry of type I superluminous supernova 2020znr
F. Poidevin, C. M. B. Omand, I. Pérez-Fournon +5
Optical imaging polarimetry was conducted on the hydrogen poor superluminous supernova 2020znr during 3 phases after maximum light (approximately +34 days, +288 days and +289 days)…
A glint in the eye: photographic plate archive searches for non-terrestrial artefacts
Beatriz Villarroel, Lars Mattsson, Hichem Guergouri +4
In this paper, we present a simple strategy to identify Non-Terrestrial artefacts \citep[NTAs;][]{Kopparapu} in or near geosynchronous Earth orbits (GEOs). We show that even the sm…
Exploring nine simultaneously occurring transients on April 12th 1950
Beatriz Villarroel, Geoffrey W. Marcy, Stefan Geier +6
Nine point sources appeared within half an hour on a region within 10 arcmin of a red-sensitive photographic plate taken in April 1950 as part of the historic Palomar Sky Su…
Activity of the Jupiter co-orbital comet P/2019~LD (ATLAS) observed with OSIRIS at the 10.4 m GTC
J. Licandro, J. de Leon, F. Moreno +8
Jupiter co-orbital comets have orbits that are not long-term stable. They may experience flybys with Jupiter close enough to trigger tidal disruptions like the one suffered by come…
