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

LOOKING FOR POSSIBLE DARK MATTER FREE PROGENITORS OF THE CARINA DWARF SPHEROIDAL GALAXY USING N-BODY SIMULATIONS

Momento, 2018
We present a study of the evolution of several different dark matter free possible progenitors of the Carina dSph galaxy, one of the satellites of the Milky Way, using Newtonian numerical N-body simulations.

The 3.5 keV line from stringy axions

Journal of High Energy Physics, 2017
An interesting result in particle astrophysics is the recent detection of an unexplained 3.5 keV line from galaxy clusters. A promising model, which can explain the morphology of the signal and its non-observation in dwarf spheroidal galaxies, involves a

Asymptotic Giant Branch Stars in the Sculptor Dwarf Spheroidal Galaxy

, 2011
JHK_S photometry is presented for a 35 arcmin square field centred on the Sculptor dwarf spheroidal galaxy. With the aid of published kinematic data definite galaxy members are identified and the width in J-K of the colour-magnitude diagram is shown to ...

A Vast Thin Plane of Co-rotating Dwarf Galaxies Orbiting the Andromeda Galaxy

, 2013
Dwarf satellite galaxies are thought to be the remnants of the population of primordial structures that coalesced to form giant galaxies like the Milky Way.

A UNIVERSAL MASS PROFILE FOR DWARF SPHEROIDAL GALAXIES?

The Astrophysical Journal, 2009
Replacement provides corrections to values of half-light radii adopted for eight classical dSphs, including revised tables and figures (conclusions are unchanged).

Search for gamma-ray emission from the nearby dwarf spheroidal galaxies with 9 years of Fermi-LAT data

, 2018
In this work, we search for $\gamma$-ray emission from the directions of some nearby Milky Way dwarf spheroidal galaxies (dSphs) and candidates with the publicly-available Pass 8 data of Fermi-LAT.
