Welcome to the EGAMI Group at Steward
Observatory, The University of Arizona!
(EGAMI = Extragalactic Astronomy with
Multiple/Multiwavelength Interests)
Observational astronomy at longer
wavelengths (> 1 µm; infrared, submillimeter,
millimeter, and radio) is currently undergoing a phase
of dramatic progress, which may be considered as its
golden age. In recent years, we saw successive
launches of two powerful infrared (IR) and submillimeter
space observatories, NASA's Spitzer
(2003) and ESA's Herschel
(2009). Since 2009, NASA's Hubble
has also been equipped with a sensitive near-IR
instrument, WFC3. In addition, three all-sky survey
satellites were launched: JAXA's Akari (2006), ESA's Planck (2009), and NASA's WISE (2009). Development on
the ground has equally been impressive: new facilities
such as EVLA, ALMA, and LMT
have started operations while existing facilities (e.g.,
CSO, JCMT, APEX,
IRAM30m, PdB, SMA, CARMA,
GBT, not to mention a number of
8-10m optical/near-IR telescopes) keep generating
exciting results with upgraded instrumentation. SOFIA
also had the first series of science flights in 2010.
This exciting era will continue well into the next
decade with JWST and SPICA in space and CCAT,
NOEMA, and TMT/GMT
on the ground.
The main scientific focus of our group
is to take advantage of these new powerful observing
capabilities at longer wavelengths and to investigate
properties of galaxies from low to high redshift.
Currently, our research actitivies are mostly driven by
large space observing programs with Hubble, Spitzer, and
Herschel, but we also conduct extensive imaging &
spectroscopic observatinos using large telescopes on the
ground such as MMT, Magellan, and LBT.
Many of our on-going projects are multi-wavelength in
nature, utilizing information from X-ray to radio.
Our scientific interests are as diverse as the
telescopes & instruments we use. The following is a
list of science topics our group members are actively
working on at present:
(1) z>6 galaxies and cosmic reionization
(2) High-redshift (z>1) IR-luminous galaxies
(3) Mass assembly and galaxy evolution in massive galaxy
clusters
(4) IR-luminous brightest cluster galaxies (BCGs) and
cluster cooling flows
(5) Use of massive galaxy clusters as powerful cosmic
telescopes
Follow the links on the left for more infomation on
individual projects. We are still in the middle of constructing this
website, so the information provided is still minimal unfortunately.
Please come back later if you do not find information you
are interested in (e.g., projects in gray).
As of August, 2011, our group includes
6 research associates, 2 graduate students, 1 research
technician, 1 undergraduate student, and a webmaster
(see the full
member list). We are somewhat different from
a typical research group in that we do not focus on any
particular science field. Instead, our guiding
principle is that we follow our interests and work on
whatever fascinates us without being constrained by our
own expertise or experinece (we are always ready to jump
into a new field or a new wavelength regime when
necessary). As a result, our group consists of
researchers with diverse scientific/technical interests
and backgrounds, working together in a stimulating (as
well as relaxed and friendly!) environment. We
always welcome to our group new members (undergrads,
grads, and post-docs), so if you're interested to work
with us and share the excitement, please contact Eiichi
Egami (eegami@as.arizona.edu) or anyone on the member
list.
