Photometric and spectroscopic variability of the blue supergiant rho Leo
V. A. Checha, A. Aret, I. Kolka +12
Context. The post-main-sequence evolution of massive stars remains poorly understood, particularly for blue supergiants. These objects play a crucial role in the dynamical and chem…
The hydrogen-free circumstellar interaction in the Type Ib supernova 2021efd: A clue to the mechanism of the helium-layer stripping
N. Pyykkinen, T. Nagao, H. Kuncarayakti +27
Stripped-envelope supernovae (SESNe), including Type IIb, Ib, and Ic supernovae (SNe), originate from the explosions of massive stars whose outer envelopes have been largely remove…
Stellar Evolution in Close Binaries: Processes and Outcomes
O. G. Benvenuto, M. A. De Vito, L. Bartolomeo Koninckx +3
We discuss some aspects of stellar evolution in binary systems. While single stars can swell following the chemical evolution of their interior, stars belonging to binary systems c…
Bosonization solution of the Kondo lattice in a Luttinger liquid
Tomás Bortolin, C. J. Bolech, Nayana Shah +1
We address the physics of a regular arrangement of independent magnetic impurities embedded in a band of interacting electrons. We focus on the one-dimensional case that can be stu…
Measurement of the top-quark mass using decays with a meson at 13 TeV with the ATLAS detector
ATLAS Collaboration
The top-quark mass is measured using top-quark decays producing an isolated lepton and meson reconstructed in its decay mode. The data sample was recorded with the A…
Search for signatures of electroweakinos with photons, jets, and large missing transverse momentum in TeV pp collisions with the ATLAS detector
ATLAS Collaboration
A search for final states characterised by at least one isolated high transverse-momentum photon, jets and large missing transverse momentum is presented. Such a final state might…
Search for higgsinos in compressed mass spectra using low-momentum tracks in collisions at TeV with the ATLAS detector
ATLAS Collaboration
This paper presents two searches for the electroweak production of higgsinos with compressed mass spectra using 140 fb of TeV proton-proton collision data coll…
Measurement of reactor antineutrino oscillations with 1.46 ktonne-years of data at SNO+
M. Abreu, A. Allega, M. R. Anderson +108
The SNO+ Collaboration reports new results on reactor antineutrino oscillations using data acquired from May 2022 through July 2025. The spectral analysis of a flux dominated by nu…
Born-Infeld Electrogravity and Dyonic Black Holes
Guadalupe Ahumada Acuña, Cecilia Bejarano, Rafael Ferraro
Born-Infeld electrogravity is defined through a Lagrangian that couples gravity and electromagnetism within a single determinantal structure. The field equations are derived in Pal…
Targeting cluster galaxies for the 4MOST CHANCES Low-z sub-survey with photometric redshifts
Hugo Méndez-Hernández, Ciria Lima-Dias, Antonela Monachesi +54
The evolution of galaxies is shaped by both internal processes and their external environments. Galaxy clusters and their surroundings provide ideal laboratories to study these eff…
Tidally-induced radial migration waves in LMC-like galaxies
Dylan Hebrail, Óscar Jiménez-Arranz, Santi Roca-Fàbrega
Stellar radial migration has predominantly been examined in isolated disc galaxies where non-axisymmetric structures drive the process. By contrast, while tidal interactions are kn…
A decade of transit photometry for K2-19: Revised system architecture
J. M. Almenara, R. Mardling, A. Leleu +21
The star K2-19 hosts a pair of Neptunian planets deep inside the 3:2 resonance. They induce strong transit-timing variations with two incommensurate frequencies. Previous photodyna…
Constraints on effective field theories via quadruple-differential angular decay rates from -channel single-top-quark production at TeV with the ATLAS detector
ATLAS Collaboration
Events with -channel single top quarks are used to probe effective field theory operators in TeV proton-proton collision data corresponding to 140 fb record…
Strong Coupling beyond the High-Q Limit and Linewidth Narrowing in a Multi-Exciton Planar Microcavity
E. A. Cerda-Méndez, Y. G. Rubo, K. Biermann +3
We systematically study the linewidths of multilevel exciton-polariton modes as a function of the detuning in a planar hybrid microcavity (MC) with low quality factor (Q~300) opera…
Search for emerging jets in collisions at TeV with the ATLAS experiment
ATLAS Collaboration
A search is presented for emerging jets using 140 fb of proton-proton collision data at TeV, collected by the ATLAS experiment between 2015 and 2018. The sea…
Similarities and differences of typicality in quantum and classical systems
Peter Reimann, Nicolas Nessi
Typicality is a well-established and very general property of quantum many-body systems, referring to the phenomenon that the expectation values of any given observable are practic…
Search for UHE neutrinos from GRBs with the Pierre Auger Observatory
Yago Lema-Capeans
We report on the search for ultra-high-energy neutrinos from the prompt emission of gamma-ray bursts (GRBs) using Surface Detector (SD) data from Phase I of the Pierre Auger Observ…
First direct detection of an RR Lyrae star conclusively associated with an intermediate-age cluster
Cecilia Mateu, Bolivia Cuevas-Otahola, Juan José Downes
RR Lyrae stars have long been considered unequivocal tracers of old (>10 Gyr) and metal-poor () stellar populations. First, because these populations are wher…

ATLAS Collaboration
The top-quark Yukawa coupling is extracted from the distribution of the top-quark pair () invariant mass in proton-proton collisions using 140 of data a…
