Time-dependent modelling of short-term variability in the TeV-blazar VER J0521+211 during the major flare in 2020
MAGIC Collaboration, S. Abe, J. Abhir +228
The BL Lacertae object VER J0521+211 underwent a notable flaring episode in February 2020. A short-term monitoring campaign, led by the MAGIC (Major Atmospheric Gamma Imaging Chere…
The Success of Optical Variability in Uncovering AGNs in Low-stellar Mass Galaxies
S. Bernal, P. Sánchez-Sáez, P. Arévalo +3
We used random forest algorithms to classify all objects in a large portion of the sky, using optical light curves obtained, or built from images provided, by the Zwicky Transient…
Investigating chemical variations between interstellar gas clouds in the Solar neighbourhood
T. Ramburuth-Hurt, A. De Cia, J. -K. Krogager +6
The interstellar medium (ISM) is a fundamental component of the Milky Way. Studying its chemical composition and the level of its chemical diversity gives us insight into the evolu…
Multiplicity of Galactic Cepheids from long-baseline interferometry V. High-accuracy orbital parallax and mass of SU Cygni
A. Gallenne, N. R. Evans, P. Kervella +23
Cepheid masses are particularly necessary to help solving the mass discrepancy, while independent distance determinations provide crucial test of the period-luminosity relation and…
Multi-wavelength study of OT 081: broadband modelling of a transitional blazar
MAGIC Collaboration, H. Abe, S. Abe +270
OT 081 is a well-known, luminous blazar that is remarkably variable in many energy bands. We present the first broadband study of the source which includes very-high-energy (VHE, $…
Hidden by a star: the redshift and the offset broad line of the Flat Spectrum Radio Quasar PKS 0903-57
P. Goldoni, C. Boisson, S. Pita +5
Context: PKS 0903-57 is a little-studied gamma-ray blazar which has recently attracted considerable interest due to the strong flaring episodes observed since 2020 in HE (100 MeV <…
FRB 20121102A monitoring: Updated periodicity in the L band
C. A. Braga, M. Cruces, T. Cassanelli +5
FRB 20121102A was the first fast radio burst to be observed to repeat. Since then, thousands of bursts have been detected by multiple radio telescopes around the world. Previous wo…
The rich galactic environment of a H-absorption selected quasar
F. Urbina, P. Noterdaeme, T. A. M. Berg +3
We present the first VLT/MUSE observations of a quasar featuring a proximate molecular absorption system, SDSS J125917.31+030922.5. The proximate damped Ly absorption acts as a…
A Benchmark JWST Near-Infrared Spectrum for the Exoplanet WASP-39b
A. L. Carter, E. M. May, N. Espinoza +77
Observing exoplanets through transmission spectroscopy supplies detailed information on their atmospheric composition, physics, and chemistry. Prior to JWST, these observations wer…
SDSS-V Local Volume Mapper (LVM): A Glimpse into Orion
K. Kreckel, O. V. Egorov, E. Egorova +37
The Orion Molecular Cloud complex, one of the nearest (D = 406 pc) and most extensively studied massive star-forming regions, is ideal for constraining the physics of stellar feedb…
Identification of 40 gravitationally magnified stars in a galaxy at redshift of 0.725
Yoshinobu Fudamoto, Fengwu Sun, Jose M. Diego +44
Strong gravitational magnifications enable to detect faint background sources, resolve their internal structures, and even identify individual stars in distant galaxies. Highly mag…
Cepheids with giant companions. II. Spectroscopic confirmation of nine new double-lined binary systems composed of two Cepheids
Bogumił Pilecki, Ian B. Thompson, Felipe Espinoza-Arancibia +13
Binary Cepheids with giant companions are crucial for studying the physical properties of Cepheid variables, providing the best means to measure their masses. Systems composed of t…
A New Precise Determination of the Primordial Abundance of Deuterium: Measurement in the metal-poor sub-DLA system at z=3.42 towards quasar J1332+0052
P. A. Kislitsyn, S. A. Balashev, M. T. Murphy +3
The theory of Big Bang nucleosynthesis, coupled with an estimate of the primordial deuterium abundance (D/H)_pr, offers insights into the baryon density of the Universe. Independen…
The Baade-Wesselink projection factor of RR Lyrae stars -- Calibration from OHP/SOPHIE spectroscopy and Gaia DR3 parallaxes
Garance Bras, Pierre Kervella, Boris Trahin +10
The application of the parallax of pulsation (PoP) technique to determine distances of pulsating stars implies the use of a scaling parameter, the projection factor (p-factor), req…
Active Galactic Nuclei in a Mid-Infrared Selected Galaxy Sample at z>0.13: [Ne V]3426 Line Emission as a Benchmark
Zi-Jian Li, Y. Sophia Dai, Jia-Sheng Huang +2
We present a 24 um-selected spectroscopic sample z > 0.13 (median z = 0.41) in the Lockman Hole field, consisting of 4035 spectra. Our aim is to identify AGNs and determine their f…
