JWST-ALMA Study of a Hub-Filament System in the Nascent Phase
N. K. Bhadari, L. K. Dewangan, O. R. Jadhav +7
Star clusters, including high-mass stars, form within hub-filament systems (HFSs). Observations of HFSs that remain unaffected by feedback from embedded stars are rare yet crucial…
Fate and detectability of rare gas hydride ions in nova ejecta: A case study with nova templates
Milan Sil, Ankan Das, Ramkrishna Das +6
HeH was the first heteronuclear molecule to form in the metal-free Universe after the Big Bang. The molecule gained significant attention following its first circumstellar dete…
Near-infrared spectroscopy of the LMC recurrent nova LMCN 1968-12a
A. Evans, D. P. K. Banerjee, T. R. Geballe +5
We have obtained near-infrared (m) spectra of the recurrent nova LMCN 1968-12a on two occasions during its 2024 August eruption. This is the first near-infrared spectro…
Field-free Josephson diode effect in interacting chiral quantum dot junctions
Debika Debnath, Paramita Dutta
We investigate chiral quantum dot (QD)-based Josephson junction and show the correlation-induced Josephson diode effect (JDE) in it. The presence of electron-electron interaction s…
Radiative Mass Mechanism: Addressing the Flavour Hierarchy and Strong CP Puzzle
Gurucharan Mohanta
We propose a class of models based on the parity invariant Left-Right Symmetric Model (LRSM), which incorporates the mechanism of radiative generation of fermion masses while simul…
Collider fingerprints of freeze-in dark matter produced during the fast expansion phase of Universe
Anupam Ghosh, Partha Konar, Sudipta Show
We examine a simple dark sector extension where the observed dark matter (DM) abundance arises from a freeze-in process through the decay of heavy vector-like quarks into a scalar…
Search for a Hidden Sector Scalar from Kaon Decay in the Di-Muon Final State at ICARUS
ICARUS Collaboration, F. Abd Alrahman, P. Abratenko +191
We present a search for long-lived particles (LLPs) produced from kaon decay that decay to two muons inside the ICARUS neutrino detector. This channel would be a signal of hidden s…
Beamsplitter-free, high bit-rate, quantum random number generator based on temporal and spatial correlations of heralded single-photons
Ayan Kumar Nai, Amritash Sharma, Vimlesh Kumar +4
The spontaneous parametric down-conversion (SPDC), an inherently random quantum process, produces a non-deterministic photon-pair with strong temporal and spatial correlations owin…
The Gaia Ultracool Dwarf Sample -- IV. GTC/OSIRIS optical spectra of Gaia late-M and L dwarfs
W. J. Cooper, H. R. A. Jones, R. L. Smart +20
As part of our comprehensive, ongoing characterisation of the low-mass end of the main sequence in the Solar neighbourhood, we used the OSIRIS instrument at the 10.4 m Gran Telesco…
Identifying Bogoliubov Fermi surfaces via thermoelectric response in a -wave superconductor heterostructure
Amartya Pal, Paramita Dutta, Arijit Saha
We theoretically investigate the thermoelectric response of Bogoliubov Fermi surfaces (BFSs) generated in a two dimensional unconventional -wave superconductor subjected to an e…
Conservation of angular momentum on a single-photon level
Lea Kopf, Rafael Barros, Shashi Prabhakar +2
Identifying conservation laws is central to every subfield of physics, as they illuminate the underlying symmetries and fundamental principles. A prime example can be found in quan…
Discovery and characterization of a dense sub-Saturn TOI-6651b
Sanjay Baliwal, Rishikesh Sharma, Abhijit Chakraborty +13
We report the discovery and characterization of a transiting sub-Saturn exoplanet TOI-6651b using PARAS-2 spectroscopic observations. The host, TOI-6651 (), is a…
Peering into the Heart of the Giant Molecular Cloud G148.24+00.41: A Deep Near-infrared View of the Newly Hatched Cluster FSR 655
Vineet Rawat, M. R. Samal, D. K. Ojha +5
We present a detailed near-infrared study of an embedded cluster located in the hub of the giant molecular cloud G148.24+00.41 of mass 10 , with the TANSPEC inst…
Linear polarization study of open clusters towards the anticenter direction: Signature of the spiral arms
Namita Uppal, Shashikiran Ganesh, Vincent Pelgrims +2
Our objective is to investigate the distribution of dust and associated large-scale structures of the Galaxy using optical linear polarization measurements of various open clusters…
Angular dependent measurement of electron-ion recombination in liquid argon for ionization calorimetry in the ICARUS liquid argon time projection chamber
ICARUS collaboration, P. Abratenko, N. Abrego-Martinez +178
This paper reports on a measurement of electron-ion recombination in liquid argon in the ICARUS liquid argon time projection chamber (LArTPC). A clear dependence of recombination o…
On the Response of the Transition Region and the Corona to Rapid Excursions in the Chromosphere
Ravi Chaurasiya, Ankala Raja Bayanna, R. E. Louis +2
Spicules are the thin hair/grass-like structures that are prominently observed at the chromospheric solar limb. It is believed that fibrils and rapid blueshifted and redshifted exc…
Modeling the Plasma Composition of 67P/C-G at different Heliocentric Distances
Sana Ahmed, Vikas Soni
The Rosetta spacecraft accompanied the comet 67P/C-G for nearly 2 years, collecting valuable data on the neutral and ion composition of the coma. The Rosetta Plasma Consortium (RPC…
Heavy Neutral Lepton searches at an ICARUS-like detector using NuMI beam
Animesh Chatterjee, Josu Hernandez-Garcia, Albert De Roeck
The discovery of non-zero neutrino masses points to the likely existence of multiple SM neutral fermions. When such states are heavy enough that they cannot be produced in oscillat…
