IoA Seminar 2014 / 2014年度・東京大学・天文学教育研究センター・談話会†
次回以降の談話会†
第259回: 2015/2/16 (Mon) 14:00-15:00†
Speaker: Kevin Bundy (IPMU, U.Tokyo)†
Title: MaNGA: Mapping Nearby Galaxies at APO An IFU Survey of 10,000 Galaxies†
I will discuss the design and execution of a new survey to obtain resolved spectroscopy
for 10,000 nearby galaxies called MaNGA (Mapping Nearby Galaxies at Apache Point Observatory).
One of three core programs in the 6-year SDSS-IV project that began on July 1st, 2014,
MaNGA will deploy 17 fiber-bundle IFUs across the Sloan 2.5m Telescope's 3 degree field-of-view,
targeting a mass-selected sample with a median redshift of 0.03, typical spatial resolution of 1-2 kpc,
and a per-fiber signal-to-noise ratio of 4-8 in the outskirts of target galaxies. For each galaxy
in the sample, MaNGA will provide maps and measured gradients of the composition
and dynamics of both stars and gas. I will present early results using a prototype instrument
that highlight MaNGA's potential to shed light on the ionization and chemical enrichment of gas
in galaxies, spatial patterns in their star formation histories, and the internal makeup of
stellar populations. MaNGA's unprecedented data set will not only provide powerful new
insight on galaxy formation and evolution but will serve as a valuable benchmark for future
high-z observations from large telescopes as well as JWST.
第260回: 2015/2/19 (Thu) 15:30-16:30†
Speaker: Wiphu Rujopakarn (IPMU, U.Tokyo)†
Title: Resolving the Obscured Cosmic Accretion History and Modes of Galaxy Assembly†
Dust obscuration has hidden at least half of the cosmic accretion
activity and concealed the most intense sites of star formation during
the peak epoch for both processes in galaxy evolution at 1 < z < 3.
Centimetric radio interferometry is the only means of identifying the
AGNs and tracing star-forming activities at sub-arcsecond resolution,
in an extinction-independent manner. I will discuss the use of radio
survey to study star formation and AGN at 1 < z < 3, focusing on the
early results from two ultra-deep 4-8 GHz Jansky VLA (JVLA) radio
observations at 0.3" resolution in the UDS and HUDF fields. The goals
of these surveys are to combine the radio data with the existing
panchromatic observations to produce a complete census of AGN and to
spatially resolve the star-forming galaxies. The ongoing survey in the
HUDF, in particular, will reach 0.3 microJy/beam RMS and will provide
the definitive radio dataset for spatially-resolved, ultra-deep,
broadband extragalactic studies until the SKA era.
