Optical spectral characterization of OP 313. Constraining the contribution of thermal and non-thermal optical emission
J. Otero-Santos, M. Nievas Rosillo, J. A. Acosta-Pulido +1
The quasar OP 313 was discovered in December 2023 in very-high-energy rays above 100 GeV, enabling for the first time a complete characterization of its emission. However, the…
Distance estimation of gamma-ray emitting BL Lac objects from imaging observations
K. Nilsson, V. Fallah Ramazani, E. Lindfors +13
Direct redshift determination of BL Lac objects is highly challenging as the emission in the optical and near-infrared (NIR) bands is largely dominated by the non-thermal emission…
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…
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)…
Optical spectral characterization of the gamma-ray blazars S4 0954+65, TXS 1515-273 and RX J0812.0+0237
J. Becerra González, J. A. Acosta-Pulido, W. Boschin +4
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 key to understand th…
Testing emission models on the extreme blazar 2WHSP J073326.7+515354 detected at very high energies with the MAGIC telescopes
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +173
Extreme high-energy peaked BL Lac objects (EHBLs) are an emerging class of blazars. Their typical two-hump structured spectral energy distribution (SED) peaks at higher energies wi…
