Collaborative analysis of data acquired from Japan's Subaru Telescope and the U.S. data : observation of clustering process of galaxies
Growing Galaxies (= Myself) And Its Surrounding Environment
“Observation of Distant Galaxy” is the area of my research specialty.
When it comes to the vast cosmic scale, looking at the far distance in space
is the same as looking at the past. I am observing the Distant Space, which
correspond to 100 billions of years ago in time, the era that the galaxies
were at evolutionary stage (did you know that the galaxies also evolve from
baby or kid galaxies to adult galaxies?)
My research theme that I intend to conduct through the Brain Circulation
Program is “to clarify the environmental dependency of the galaxies in the
distant space”. The environmental dependency is phenomena that properties of
galaxies depend on where they live (at a congested region or isolated region
and etc.). Just like human beings, galaxies are expected to have followed
different growing process reflecting its birthplace or where it grew up.
We anticipate that investigating these environmental dependencies will help
us to understand the physical mechanism of Galaxy Formation and Evolution.
There are two essential factors to investigate the above:
1) “observations in wide field” and
2) “as close as possible to data at infrared wavelength range”.
Wide field observation is one of the strength that Japan’s Subaru telescope
offers, and our galaxy research group centered by Tohoku University has been
receiving the benefit of having access to this powerful telescope in the world.
The research group of Professor Fazio at CfA, who I will be working with,
is the team developed the Infrared Array Camera (IRAC) mounted on the Spitzer
Space Telescope and to exert a pull of infrared astronomy by using amazing data
acquired from IRAC. I am hoping that my visit to CfA can add a possiblity,
by combining the strength of both US and Japanese research groups,
to expand science that no other in the world has ever approached.
Being the youngest researcher among the visiting teams, I am worried a little
if I can get by all right in a foreign country alone. But, at the same time
I know that I will enjoy such fortunate environment of being able to receive
valuable supports from this US-Japan teams comprising of the extremely prominent
researchers. Taking an advantage of youngness I have nothing to lose now.
So, I would like to challenge anything fearlessly. Unlike the galaxies,
I believe that we human beings can change depending on how you see the
environment being placed on.
