SDSS-IV MaStar: Determination of Stellar Parameters Using Bayesian Averaging
Yan-Ping Chen, Renbin Yan, Szabolcs Mészáros +12
We present the stellar parameters for 59,266 high-quality spectra of 24,130 unique stars from the MaNGA Stellar Library (MaStar) in the Sloan Digital Sky Survey (SDSS) Data Release…
SN 2022erq: A Superluminous Thermonuclear Supernova with Escalating Preexplosion Mass Loss
Qian Zhai, Jujia Zhang, Xiaofeng Wang +51
We present a photometric and spectroscopic study of the superluminous Type Ia supernova SN 2022erq. Its early spectra, dominated by iron-group elements with weak intermediate-mass…
Asteroseismic Analysis of the Merger Product Red Giant in the Persei System
Rozália Z. Ádám, László Molnár, Róbert Szabó +7
Context. Persei is a long-period eclipsing binary system ( years) containing a red giant primary, and it is well known for its multi-faceted classification as a…
Topological Hall Effect in Antiferromagnetic Co doped FeGaTe
Shyam Raj Karullithodi, Yeonkyu Lee, Vadym Kulichenko +8
FeGaTe is van der Waals (vdW) ferromagnet with a Curie temperature ranging from 350 K to 380 K, followed upon cooling by a ferrimagnetic transition near room temperat…
Anatomy of the modern theory of orbital magnetism from first-principles: term-by-term analysis in the gauge-covariant formalism
Hojun Lee, Insu Baek, Mirco Sastges +3
We present an in-depth analysis of the orbital magnetism by means of the so-called modern theory based on the Berry phase across distinct classes of materials-d transition metals,…
The extremely low-luminosity Type Iax SNe 2022ywf and 2023zgx
Barnabás Barna, Dominik Bánhidi, Tamás Szalai +25
We present the optical follow-up of SNe 2022ywf and 2023zgx, two examples from the Iax subclass of thermonuclear supernova (SN) events. With peak absolute magnitudes of $M_\mathrm{…
Integrated Sachs-Wolfe maps from the Gower Street CDM simulations
Mina Ghodsi Yengejeh, András Kovács, István Szapudi +1
The late-time linear Integrated Sachs-Wolfe (ISW) effect directly probes the dynamics of cosmic acceleration and the nature of dark energy. Detecting these weak, secondary temperat…
Multiband neural network classification of ZTF light curves as LSST proxies
Tamás Szklenár, Attila Bódi, Róbert Szabó
In this project we use data obtained by Zwicky Transient Facility to develop and test a neural-network-based, multiband classification algorithm to classify periodic variable stars…
Tuning proximity-induced spin-orbit coupling in graphene/WSe heterostructures
Tobias Rockinger, Bálint Szentpéteri, Szabolcs Csonka +10
Recently, proximity-induced spin-orbit coupling (SOC) has been observed in heterostructures consisting of monolayer graphene (ML-G) and transition metal dichalcogenides (TMDCs) suc…
Dynamical Orbital Angular Momentum Induced by Circularly Polarized Phonons
Dapeng Yao, Dongwook Go, Yuriy Mokrousov +1
We show that the orbital angular momentum (OAM) of electrons is dynamically induced by circularly polarized phonons. The induced OAM originates from the adiabatic evolution in whic…
Rare Find: Discovery and chemo-dynamical properties of two s-process enhanced RR Lyrae stars
Valentina D'Orazi, Giuliano Iorio, Borbála Cseh +15
We report the serendipitous discovery of two RR Lyrae stars exhibiting significant s-process element enrichment, a rare class previously represented solely by TY Gruis. Our goal is…
Hidden massive eclipsing binaries in red supergiant systems: The hierarchical triple system KQ Puppis and other candidates
D. Jadlovský, L. Molnár, A. Ercolino +26
The majority of massive stars are part of binary systems that may interact during their evolution. However, not many RSGs are known binaries, and only a few have constrained orbita…
Tracing the high-z cosmic web with Quaia: catalogues of voids and clusters in the quasar distribution
Nestor Arsenov, Andras Kovacs, Mar Perez Sar +5
Understanding the formation and evolution of the cosmic web of galaxies is a fundamental goal of cosmology, using various tracers of the cosmic large-scale structure at an ever wid…
Is it worth the effort to find Lefschetz thimbles? Integration contours with numerically optimal signal-to-noise ratios in simple fermionic toy models
Attila Pasztor, David Pesznyak
We perform a detailed analysis of the fermionic sign problem in a series of one dimensional integrals, that are achieved as extreme (one-site) limits of genuine physics models. Alt…
