Tidal Grinding of Dwarf Galaxies in Cluster Environments
Sanjaya Paudel, Suk-Jin Yoon, Tek Prasad Adhikari +4
Dwarf elliptical galaxies (dEs) dominate galaxy clusters and provide key constraints on environmentally driven galaxy evolution. Here we examine whether the projected shapes of dEs…
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. The…
Discovery of a Rare Group of Dwarf Galaxies in the Local Universe
Sanjaya Paudel, Cristiano G. Sabiu, Suk-Jin Yoon +3
We report the discovery of a rare isolated group of five dwarf galaxies located at z = 0.0086 ( = 36 Mpc). All member galaxies are star-forming, blue, and gas-rich with in…
Moving Groups in the Solar Neighborhood with Gaia, APOGEE, GALAH, and LAMOST: Dynamical Effects Gather Gas and the Ensuing Star Formation Plays an Important Role in Shaping the Stellar Velocity Distributions
Xilong Liang, Suk-Jin Yoon, Jingkun Zhao
With Gaia, APOGEE, GALAH, and LAMOST data, we investigate the positional, kinematic, chemical, and age properties of nine moving groups in the solar neighborhood. We find that each…
On the Migration Origin of the Hercules Moving Group with GAIA, LAMOST, APOGEE, and GALAH Surveys
Xilong Liang, Suk-Jin Yoon, Jingkun Zhao +3
Using Gaia DR3 data and the wavelet transformation technique, we study the substructures of the Hercules moving group (HMG): Hercules 1 (H1) and Hercules 2 (H2). Spectroscopic surv…
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,…
UV Properties of Galactic Globular Clusters with GALEX I. The Color-Magnitude Diagrams
Ricardo P. Schiavon, Emanuele Dalessandro, Sangmo T. Sohn +10
We present GALEX data for 44 Galactic globular clusters obtained during 3 GALEX observing cycles between 2004 and 2008. This is the largest homogeneous data set on the UV photometr…
