A Complete 16 micron-Selected Galaxy Sample at : Mid-infrared Spectral Energy Distributions
J. -S. Huang, Y. -S. Dai, S. P. Willner +21
We describe a complete, flux-density-limited sample of galaxies at redshift selected at 16 micron. At the selection wavelength near 8 micron rest, the observed emis…
UV and NIR size of the low-mass field galaxies: the UV compact galaxies
Cheng Cheng, Cong Kevin Xu, Lizhi Xie +10
Most of the massive star-forming galaxies are found to have `inside-out' stellar mass growth modes, which means the inner parts of the galaxies mainly consist of the older stellar…
Detailed chemical composition and orbit of the new globular cluster FSR1758: Implications for the accretion of the Sequoia dwarf galaxy onto the Milky Way
Sandro Villanova, Lorenzo Monaco, Julia O'Connell +4
We present detailed chemical abundances, radial velocities and orbital parameters for FSR 1758, a recently discovered star cluster in the direction of the Galactic Bulge. High reso…
NGC 6791: a probable bulge cluster without multiple populations
Sandro Villanova, Giovanni Carraro, Douglas Geisler +2
NGC 6791 is a unique stellar cluster, key to our understanding of both the multiple stellar population phenomenon and the evolution and assembly of the Galaxy. However, despite man…
A possible formation scenario for dwarf spheroidal galaxies - III. Adding star formation histories to the fiducial model
A. G. Alarcon Jara, M. Fellhauer, D. R. Matus Carillo +3
Dwarf spheroidal galaxies are regarded as the basic building blocks in the formation of larger galaxies and are believed to be the most dark matter dominated systems known in the U…
A spectroscopic study of the Globular Cluster NGC 4147
Sandro Villanova, Lorenzo MOnaco, Cristian Moni Bidin +1
We present the abundance analysis for a sample of 18 red giant branch stars in the metal-poor globular cluster NGC 4147 based on medium and high resolution spectra. This is the fir…
Block Time Step Storage Scheme for Astrophysical N-body Simulations
Maxwell Xu Cai, Yohai Meiron, M. B. N. Kouwenhoven +2
Astrophysical research in recent decades has made significant progress thanks to the availability of various -body simulation techniques. With the rapid development of high-perf…
Phase mixing due to the Galactic potential: steps in the position and velocity distributions of popped star clusters
G. N. Candlish, R. Smith, M. Fellhauer +3
As star clusters are expected to form with low star formation efficiencies, the gas in the cluster is expelled quickly and early in their development: the star cluster "pops." This…
A Possible Formation Scenario for Dwarf Spheroidal Galaxies - II: A Parameter Study
P. Assmann, M. Fellhauer, M. I. Wilkinson +2
Dwarf spheroidal (dSph) galaxies are considered the basic building blocks of the galaxy formation process in the LCDM (Lambda Cold Dark Matter) hierarchical cosmological model. The…
A Possible Formation Scenario for Dwarf Spheroidal Galaxies I: Fiducial Model
Paulina Assmann, Michael Fellhauer, Mark I. Wilkinson +1
We use numerical simulations to study a formation scenario for dwarf spheroidal galaxies in which their stellar populations are the products of the dissolution of open star cluster…
Infant mortality in the hierarchical merging scenario: Dependency on gas expulsion timescales
Rory Smith, Simon Goodwin, Michael Fellhauer +1
We examine the effects of gas expulsion on initially sub-structured and out-of-equilibrium star clusters. We perform N-body simulations of the evolution of star clusters in a stati…
Ram pressure drag - the effects of ram pressure on dark matter and stellar disk dynamics
R. Smith, M. Fellhauer, P. Assmann
We investigate the effects of ram pressure stripping on gas-rich disk galaxies in the cluster environment. Ram pressure stripping principally effects the atomic gas in disk galaxie…
Formation rates of star clusters in the hierarchical merging scenario
R. Smith, R. Slater, M. Fellhauer +2
Stars form with a complex and highly structured distribution. For a smooth star cluster to form from these initial conditions, the star cluster must erase this substructure. We stu…
Popping star clusters as building blocks of the Milky Way Thick Disc
P. Assmann, M. Fellhauer, P. Kroupa +2
It is widely believed that star clusters form with low star formation efficiencies. With the onset of stellar winds by massive stars or finally when the first super nova blows off,…
A parametric study on the formation of extended star clusters and ultra-compact dwarf galaxies
R. C. Bruens, P. Kroupa, M. Fellhauer +2
In the last decade, extended stellar clusters with masses in the range from a few 10^4 to 10^8 M_sun have been found in various types of galaxies in different environments. Objects…
Surviving infant mortality in the hierarchical merging scenario
Rory Smith, Michael Fellhauer, Simon Goodwin +1
We examine the effects of gas expulsion on initially sub-structured and out-of-equilibrium star clusters. We perform -body simulations of the evolution of star clusters in a sta…
Star Cluster collisions - a formation scenario for the Extended Globular Cluster Scl-dE1 GC1
Paulina Assmann, Mark I. Wilkinson, Michael Fellhauer +1
Recent observations of the dwarf elliptical galaxy Scl-dE1 (Sc22) in the Sculptor group of galaxies revealed an extended globular cluster (Scl-dE1 GC1), which exhibits an extremely…
Star clusters as building blocks for dSph galaxies formation
P. Assmann, M. Fellhauer, M. I. Wilkinson
We study numerically the formation of dSph galaxies. Intense star bursts, e.g. in gas-rich environments, typically produce a few to a few hundred young star clusters, within a regi…
