Galactic star formation enhanced and quenched by ram pressure in groups and clusters
Kenji Bekki
We investigate how ram pressure of intragroup and intracluster medium can influence the spatial and temporal variations of star formation (SF) of disk galaxies with halo masses (M_…
Origin of a bottom-heavy stellar initial mass function in elliptical galaxies
Kenji Bekki
We investigate the origin of a bottom-heavy stellar initial mass function (IMF) recently observed in elliptical galaxies by using chemical evolution models with a non-universal IMF…
Simulating galaxy evolution with a non-universal stellar initial mass function
Kenji Bekki
We consider that the stellar initial mass function (IMF) depends on physical properties of star-forming molecular clouds in galaxies and thereby investigate how such a non-universa…
Stripping of nitrogen-rich AGB ejecta from interacting dwarf irregular galaxies
Takuji Tsujimoto, Kenji Bekki
Dwarf irregular galaxies (dIrrs) including the Magellanic Clouds in the local Universe, in many cases, exhibit an unusually low N/O abundance ratio (log N/O ~ -1.5) in H II regions…
The VMC survey -IX. Pilot study of the proper motion of stellar populations in the LMC from 2MASS and VISTA data
M. -R. L. Cioni, L. Girardi, M. I. Moretti +9
We use multi-epoch near-infrared observations from the VISTA survey of the Magellanic Cloud system (VMC) to measure the proper motion of stars of the LMC, in one tile of 1.5 deg^2…
Stellar population gradients and spatially resolved kinematics in luminous post-starburst galaxies
M. B. Pracy, S. Croom, E. Sadler +7
We have used deep integral field spectroscopy obtained with the GMOS instrument on Gemini-North to determine the spatial distribution of the post-starburst stellar population in fo…
