Pre-heating by pre-virialization and its impact on galaxy formation
dark matter large-scale structure of the universe
2014/12/24
We use recent observations of the H i mass function to constrain galaxy formation. The data conflict with the standard model where most of the gas in a low-mass dark matter halo is assumed to settle i...
Submillimeter Wave Astronomy Satellite observations of Comet 9P/Tempel 1 and Deep Impact
Comet Tempel-1 Radiative Transfer Radio Observations Comets
2014/12/23
On 4 July 2005 at 5:52 UT the Deep Impact mission successfully completed its goal to hit the nucleus of 9P/Tempel 1 with an impactor, forming a crater on the nucleus and ejecting material into the com...
USING 21 cm ABSORPTION IN SMALL IMPACT PARAMETER GALAXY-QUASAR PAIRS TO PROBE LOW-REDSHIFT DAMPED AND SUB-DAMPED Ly alpha SYSTEMS
low-redshift damped Lyα (DLA) sub-DLA quasar absorbers
2014/12/20
To search for low-redshift damped Lyα (DLA) and sub-DLA quasar absorbers, we have conducted a 21 cm absorption survey of radio-loud quasars at small impact parameters to foreground galaxies selected f...
Galactic Bulge Feedback and its Impact on Galaxy Evolution

2014/12/9
Galactic bulges of early-type spirals and elliptical galaxies comprise primarily old stars, which account for more than half of the total stellar mass in the local Universe. These stars collectively g...

ASTEROID IMPACT MONITORING (Invited review)
Minor planets asteroids-earth-Celestial mechanics
2009/2/19
Some asteroids and comets with Earth-crossing orbit may impact
our planet, thus we need to be able to identify the cases which could have a danger-
ous close approach within a century. This must be ...
