Algebraic Structure of Three-Flavor Neutrino Oscillations in Constant-Density Matter: Cayley--Hamilton Evolution, DMP Resummation, and Closed-Form Uncertainty Propagation
Aaryan Chaulagain, Anju Dhakal, Daya Nidhi Chhatkuli
For three-flavor neutrino oscillations in constant-density matter, the Cayley--Hamilton theorem forces the evolution operator into a quadratic polynomial in , with coeffic…
Groups of Dwarf Galaxies in the Local Universe
Sanjaya Paudel, Cristiano G. Sabiu, Suk-Jin Yoon +3
We present a systematic search for dwarf-galaxy groups in the local Universe (), identifying 28 systems containing at least four spectroscopically confirmed members selecte…
A Lightning-Fast Three-Flavor Neutrino Oscillation Calculator in Constant-Density Matter with Built-In Uncertainty Propagation
Aaryan Chaulagain, Daya Nidhi Chhatkuli, Anju Dhakal
Neutrino oscillation experiments are entering an era of precision, requiring both fast calculations and reliable uncertainty estimates. We present a compact three-flavor oscillatio…
Different Origins of Nucleated and Non-nucleated Dwarf Elliptical Galaxies: Identified by the Deep-learning
Sanjaya Paudel, Cristiano G. Sabiu, Suk-Jin Yoon +4
Dwarf elliptical galaxies (dEs) are the dominant population in galaxy clusters and serve as ideal probes for studying the environmental impact on galactic evolution. A substantial…
TESS Light Curve Analysis: A Case Study of Stellar Rotation in TIC 445493624
Pratik Paudel, Daya Nidhi Chhatkuli, Bikash Sharma +3
Stellar rotation is a fundamental parameter governing a star's magnetic activity and evolution. The Transiting Exoplanet Survey Satellite (TESS) provides high-precision photometric…
Singularity reversal of Schwarzschild black holes in Anti-de-Sitter
Rakshit Poudel, Daya Nidhi Chhatkuli, Madhav Kafle
We propose a non-metastable de-Sitter infinitesimal patch as a replacement for the theoretical singularity that occurs during the description of maximally extended Schwarzschild An…
SDSS J134313.15+364457.5: Forming Compact Elliptical through the Merger
Daya Nidhi Chhatkuli, Sanjaya Paudel, Binil Aryal +3
Scaling relations are fundamental tools for exploring the morphological properties of galaxies and understanding their formation and evolution. Typically, galaxies follow a scaling…
The creation of a massive UCD by tidal threshing from NGC 936
Sanjaya Paudel, Pierre-Alain Duc, Sungsoon Lim +9
We study a compact nucleus embedded in an early-type dwarf galaxy, MATLAS-167, which is in the process of disruption by the tidal force of the neighboring giant S0 galaxy, NGC 936,…
Rejuvenating Star Formation Activity in an Early-type Dwarf Galaxy, LEDA 1915372, with Accreted HI Gas
Sanjaya Paudel, Suk-Jin Yoon, Omkar Bait +5
We report a rare astrophysical phenomenon, in which an early-type dwarf galaxy (dE), LEDA 1915372, is accreting gas from a nearby star-forming dwarf galaxy, MRK 0689, and is rejuve…
An Extensive Catalog of Early-type Dwarf Galaxies in the Local Universe: Morphology and Environment
Sanjaya Paudel, Suk-Jin Yoon, Jaewon Yoo +11
We present an extensive catalog of 5405 early-type dwarf (dE) galaxies located in the various environments, i.e., clusters, groups and fields, of the local universe ( 0.01).…
Forming Blue Compact Dwarf Galaxy (BCD) through Mergers
Daya Nidhi Chhatkuli, Sanjaya Paudel, Rajesh Kumar Bachchan +2
It has long been speculated that Blue Compact Dwarf galaxies (BCDs) are formed through the interaction between low-mass gas-rich galaxies, but a few candidates of such systems have…
Early-type Dwarf Galaxies in the Local Universe. Evidence of Ex-situ Growth
Sanjaya Paudel, Suk-Jin Yoon, Jun-Sung Moon +1
We report the discovery of a rare early-type dwarf galaxy (dE), SDSS J125651.47+163024.2 (hereafter dE1256), possessing a tidal feature that was likely built up by accretion of an…
MCG+07-20-052: Interacting dwarf pair in a group environment
Sanjaya Paudel Chandreyee Sengupta, Suk-Jin Yoon, Daya Nidhi Chhatkuli
We present an observational study of the interacting pair of dwarf galaxies, MCG+07-20-052, in the vicinity of Milky Way mass spiral galaxy NGC 2998. MCG+07-20-052 is located at a…
