My name is Anuradha Koratkar. From my name you would not know if I was a man or a
woman, so let me tell you that I am a woman. If my name had been Jane or Jill you would
have guessed, but my name is so different because I am of Indian origin. My name is the
Indian name of the brightest star in the constellation of scorpio! I came to the United
States in 1984 to study for my Ph. D. in Astronomy. I finished my Ph. D from the
University of Michigan in 1990 and since then I have been working at the Space Telescope
Science Institute. I got married 5 years ago and now have a cute baby boy. His name is
Vivek. I love to knit and bake. I am learning to scuba dive, and white water raft.
I am an instrument scientist for the Faint Object Spectrograph (FOS). The Hubble Space
Telescope (HST) has two cameras and two spectrographs. A spectrograph is an instrument
that breaks light into its individual colors, just like a prism breaks light into seven
different colors, and then measures the amount in each color. A spectrograph breaks the
light into much finer components than when a prism breaks light into the 7 components
that we see in a rainbow. This spectrograph can observe objects both in the visible
(colors that we can see with our eyes) and in the ultra-violet (UV). Why do you think it
is possible to observe in the ultra-violet with the HST since UV radiation is blocked by
the earth's atmosphere?
As an instrument scientist I have to make sure that my instrument is working properly,
so that other astronomers can use it to study their favourite objects. Since, I know how
the instrument works, I also help other astronomers to prepare their observing strategy,
i.e. a plan on how to conduct their observations with the FOS. After their observations
have been completed I help astronomers to analyze their data.
Today, I spent the day helping an astronomer ( we call them GOs or Guest Observer) to
plan observing a Seyfert Galaxy. A seyfert galaxy is an unusual kind of galaxy. In this
galaxy the nucleus has a black-hole which is giving off energy equivalent to about 10^6
suns!!
I decided I wanted to be an astronomer at a very early age. I was 10 years old when I
was taken by my grandmother to the local observatory (in Hyderabad, India) to see the
planets. I had one look at Saturn and decided I wanted to study planets when I grew up,
so I asked the local astronomer how I could prepare for a career in astronomy. I followed
his advice and obtained my bachelors in Math, Physics and Chemistry. Later I obtained my
masters in Mathematics and a Ph. D in Astronomy (at age 30). So you can see it took a
long time to attain my goals!
Although I still love to talk about the solar neighborhood (see I still sometimes
spell in British English as I was taught in India!), I got interested in the study of
quasars and did my doctoral thesis on the structure of quasars.
I love to learn new things about all the various objects that are out there in the
universe. As an instrument scientist I am involved with many GOs who are observing
interesting objects and so I get to know interesting facts about various objects. I
also love to calibrate (to study how the instrument is behaving) the FOS and to see
it change with time and when some astronomer makes a important scientific contribution
using the FOS, I feel very proud. The boring part of my job is keeping records on what
happened to the instrument. I know it is an important job (because how else would some
one know what happened to the FOS on say January 5th 1996) and I do it, but boy is it
boring.
As a kid in India I mostly did my school work and the rest of the time played with my
friends or went swimming. But during summer vacation I would go to the library and read
books on space. From these books I learned about the solar system and our galaxy the
Milky way. Then whenever it was possible I would ask my parents to take me to the
planetarium. I think that astronomy is such an adaptable subject that one can specialize
in any field of science and then apply it to the study of space, life and its origin.
My grandmother, my parents and an astronomer friend had the most influence on me. My
grandmother was a doctor (obstetrician) and my mother is a scientist (Biochemist). They
were very strong women and a lot of fun. I always wanted to be like them. Till the 1980s
in India it was unusual for women to obtain post-graduate degrees, but my grandmother and
my parents always encouraged me to do my best.
