Astrophysical site(s) of r-process elements in galactic chemodynamical evolution model

EPJ Web of Conferences, 2016
Astrophysical site(s) of rapid neutron-capture process (r-process) is (are) not identified yet. Although core-collapse supernovae have been regarded as one of the possible candidates of the astrophysical site of r-process, nucleosynthesis studies suggest

Self-interacting Dark Matter Interpretation of Crater II

The Astrophysical Journal Letters
The satellite galaxy Crater II of the Milky Way is extremely cold and exceptionally diffuse. These unusual properties are challenging to understand in the standard model of cold dark matter.

The Origin of High-velocity Stars Considering the Impact of the Large Magellanic Cloud

The Astronomical Journal
Utilizing astrometric parameters sourced from Gaia Data Release 3 and radial velocities obtained from various spectroscopic surveys, we identify 519 high-velocity stars (HiVels) with a total velocity in the Galactocentric rest frame greater than 70% of ...

Probing late-time annihilations of oscillating asymmetric dark matter via rotation curves of galaxies

European Physical Journal C: Particles and Fields
In this paper, we explore the Oscillating Asymmetric Dark Matter (OADM) model to address the core-cusp problem, aiming to resolve the discrepancy between the predictions of the $$\Lambda \textrm{CDM}$$ Λ CDM cosmological model and the observed dark ...

WFPC2 Observations of the Carina Dwarf Spheroidal Galaxy.

The Astronomical Journal, 1997
We present our analysis of Hubble Space Telescope Wide Field Planetary Camera 2 observations in F555W (~V) and F814W (~I) of the Carina dwarf spheroidal galaxy. The resulting V vs (V-I) color-magnitude diagrams reach V ~ 27.1 mag. The reddening of Carina is estimated to be E(V-I) = 0.08 +- 0.02 mag.
