Tidal Grinding of Dwarf Galaxies in Cluster Environments
Sanjaya Paudel, Suk-Jin Yoon, Tek Prasad Adhikari +4
The paper investigates how the shapes of dwarf elliptical galaxies in the Virgo cluster relate to their tidal histories, finding that flatter dwarfs are more uniformly distributed…
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…
SN Ia Population Machine. I. A Unified Cosmological Simulation-Binary Synthesis Framework Establishing Non-universal Delay-time Distributions and Cosmic Progenitor-channel Dominance Crossover
Suk-Jin Yoon, Inhyuk Park, Woong-Bae G. Zee +6
We present a forward-modeling framework for synthesizing Type Ia supernova (SN Ia) populations by coupling cosmological hydrodynamic simulations to binary population synthesis (BPS…
Living with Neighbors. V. Better-aligned Spiral+Spiral Galaxy Pairs Show Stronger Star Formation
Woong-Bae G. Zee, Jun-Sung Moon, Sanjaya Paudel +1
Enhanced star formation (SF) with star-forming neighboring galaxies bolsters hydrodynamical contributions during paired interactions. Although the relative spin orientation between…
An isolated early-type dwarf galaxy that ran away from the group environment
Sanjaya Paudel, Cristiano G. Sabiu, Suk-Jin Yoon +2
Understanding the quenching mechanisms in dwarf galaxies is crucial for constraining models of galaxy formation and evolution. In this vein, isolated dwarf galaxies offer valuable…
A New Rarity Assessment of the `Disk of Satellites': the Milky Way System Is the Exception Rather than the Rule in the CDM Cosmology
Chanoul Seo, Suk-Jin Yoon, Sanjaya Paudel +2
The majority of satellite galaxies around the Milky Way (MW) show disk-like distributions (the disk of satellites; DoS), which is a small-scale problem of the CDM cosmology. Th…
