Multiband optical variability on diverse timescales of the blazar Ton 599 from 2011 to 2023
O. Vince, C. M. Raiteri, M. Villata +72
(Shortened)Context: We analyze the optical variability of the FSRQ Ton 599 using BVRI photometry from the WEBT collaboration (2011-2023), complemented by photometric and spectrosco…
Primordial magnetic field from chiral plasma instability with sourcing
Murman Gurgenidze, Andrew J. Long, Alberto Roper Pol +2
In an electron-positron plasma, an imbalance in the number of right- and left-chiral particles can lead to the growth of a helical magnetic field through a phenomenon called the ch…
On Lorentz Variability of Magnetically Dominated Relativistic Outflows
V. I. Berezhiani, N. L. Shatashvili, A. G. Tevzadze
We show that magnetized relativistic outflows can exhibit a relativistic effect in which Lorentz transformation maps spatially extended magnetic field structure into apparent tempo…
Without the Sound Horizon (or Supernovae): A 2% Measurement in DESI DR1
E. A. Zaborowski, P. Taylor, K. Honscheid +58
The sound horizon scale is a key source of information for early-time measurements, and is therefore a common target of new physics proposed to solve the Hubble tension…
Discovery and Analysis of Afterglows from Poorly Localised GRBs with the Gravitational-wave Optical Transient Observer (GOTO) All-sky Survey
Amit Kumar, B. P. Gompertz, B. Schneider +86
Gamma-ray bursts (GRBs), particularly those detected by wide-field instruments such as the Fermi/GBM, pose a challenge for optical follow-up due to their large initial localisation…
Fiducial-Cosmology-dependent systematics for the DESI 2024 Full-Shape Analysis
R. Gsponer, S. Ramirez-Solano, F. Rodríguez-Martínez +65
We assess the impact of the fiducial cosmology choice on cosmological inference from full-shape (FS) fits of the galaxy power spectrum in the DESI 2024 Data Release 1 (DR1). Using…
Combined tracer analysis for DESI 2024 BAO
D. Valcin, M. Rashkovetskyi, H. Seo +64
This paper demonstrates how the Dark Energy Spectroscopic Instrument (DESI) Data Release 1 (DR1) and future baryon acoustic oscillations (BAO) analyses can optimally combine overla…
Frequentist Cosmological Constraints from Full-Shape Clustering Measurements in DESI DR1
James Morawetz, Hanyu Zhang, Marco Bonici +53
We present a frequentist analysis of clustering measurements from Data Release 1 of the Dark Energy Spectroscopic Instrument (DESI) using the standard profile likelihood method. Wh…
JWST reveals a supernova following a gamma-ray burst at z 7.3
A. J. Levan, B. Schneider, E. Le Floc'h +50
The majority of energetic long-duration gamma-ray bursts (GRBs) are thought to arise from the collapse of massive stars, making them powerful tracers of star formation across cosmi…
Synthesizing Sun-as-a-star flare spectra from high-resolution solar observations
M. De Wilde, A. G. M. Pietrow, M. K. Druett +22
Spatially resolved observations of the Sun and the astronomical sample size of stellar bodies are the respective key strengths of solar and stellar observations. However, the large…
Model-Independent Measurement of the Matter-Radiation Equality Scale in DESI 2024
B. Bahr-Kalus, D. Parkinson, K. Lodha +52
The peak of the matter power spectrum, known as the turnover (TO) scale, is determined by the horizon size at the time of matter-radiation equality. This scale can serve as a stand…
Constraining Lens Masses in Moderately to Highly Magnified Microlensing Events from Gaia
U. Pylypenko, Ł. Wyrzykowski, P. J. Mikołajczyk +57
Microlensing events provide a unique way to detect and measure the masses of isolated, non-luminous objects, particularly dark stellar remnants. Under certain conditions, it is pos…
Dynamical Dark Energy in light of the DESI DR2 Baryonic Acoustic Oscillations Measurements
Gan Gu, Xiaoma Wang, Yuting Wang +57
Understanding whether cosmic acceleration arises from a cosmological constant or a dynamical component is a central goal of cosmology, and the Dark Energy Spectroscopic Instrument…
AT2021uey: A planetary microlensing event outside the Galactic bulge
M. Ban, P. Voloshyn, R. Adomaviciene +42
We report the analysis of a planetary microlensing event AT2021uey. The event was observed outside the Galactic bulge and was alerted by both space- (Gaia) and ground-based (ZTF an…
Limits on the Ejecta Mass During the Search for Kilonovae Associated with Neutron Star-Black Hole Mergers: A case study of S230518h, GW230529, S230627c and the Low-Significance Candidate S240422ed
M. Pillas, S. Antier, K. Ackley +78
Neutron star-black hole (NSBH) mergers, detectable via their gravitational-wave (GW) emission, are expected to produce kilonovae (KNe). Four NSBH candidates have been identified an…
DESI DR2 Results II: Measurements of Baryon Acoustic Oscillations and Cosmological Constraints
DESI Collaboration, M. Abdul-Karim, J. Aguilar +184
We present baryon acoustic oscillation (BAO) measurements from more than 14 million galaxies and quasars drawn from the Dark Energy Spectroscopic Instrument (DESI) Data Release 2 (…
The cosmological Mass Varying Neutrino model in the late universe
Olga Avsajanishvili
The cosmological Mass Varying Neutrino (MaVaN) model is considered, where the interaction between a fermionic field and a scalar field with a Ratra-Peebles potential via a Yukawa c…
