The mass-metallicity relation at z 1.4 revealed with Subaru/FMOS
(2014-02-01)
We present a stellar mass-metallicity relation at z ~ 1.4 with an unprecedentedly large sample of ~340 star-forming galaxies obtained with FibreMulti-Object Spectrograph (FMOS) on the Subaru Telescope. We observed K-band ...
Dynamical evolution of star-forming regions
(2014-02-01)
We model the dynamical evolution of star-forming regions with a wide range of initial properties. We follow the evolution of the regions' substructure using the Q-parameter, we search for dynamical mass segregation using ...
Distribution and evolution of starspots on the RS CVn binary II Pegasi in 2004
(2014-02-01)
We present Doppler images of RS CVn-type binary II Peg based on two data sets obtained in 2004 February and November. In order to improve signal-to-noise ratio and reliability,we apply least-squares deconvolution technique ...
The Herschel stripe 82 survey (HerS) : Maps and early catalog
(2014-02-01)
We present the first set of maps and band-merged catalog from the Herschel Stripe 82 Survey (HerS). Observations at 250, 350, and 500 μm were taken with the Spectral and Photometric Imaging Receiver instrument aboard the ...
Constraints on massive star formation : Cygnus OB2 was always an association
(2014-02-01)
We examine substructure and mass segregation in the massive OB association Cygnus OB2 to better understand its initial conditions. Using a well-understood Chandra X-ray selected sample of young stars, we find that Cyg OB2 ...
Star formation and agn activity in interacting galaxies : A near-UV perspective
(2014-01-21)
We study nearby galaxies in close pairs to study the key factors affecting star formation and active galactic nuclei (AGN) activity triggered during galaxy interactions. Close pairs are selected from the Sloan Digital Sky ...
NGC 1266 as a local candidate for rapid cessation of star formation
(2014-01-10)
We present new Spectrographic Areal Unit for Research on Optical Nebulae (SAURON) integral-field spectroscopy and Swift Ultraviolet Optical Telescope (UVOT) observations of molecular outflow host galaxy NGC 1266 that ...
Evolution of faint radio sources in the VIDEO-XMM3 field
(2013-12-01)
It has been speculated that low-luminosity radio-loud active galactic nuclei (AGN) have the potential to serve as an important source of AGN feedback, and may be responsible for suppressing star formation activity in massive ...
Searching for transits in the Wide Field Camera Transit Survey with difference-imaging light curves
(2013-12)
The Wide Field Camera Transit Survey is a pioneer program aiming at for searching extra-solar planets in the near-infrared. The images from the survey are processed by a data reduction pipeline, which uses aperture photometry ...
Towards precise ages and masses of free floating planetary mass brown dwarfs
(2013-11-01)
Measurement of the substellar initial mass function (IMF) in very young clusters is hampered by the possibility of the age spread of clustermembers. This is particularly serious for candidate planetary mass objects (PMOs), ...
