Light Element Abundances in the Universe
Jay
Christopher
Howk
is
an
Associate
Professor
and
Director
of
Graduate
Studies
at
the
University
of
Notre
Dame's
Department
of
Physics.
He
received
his
Ph.D.
in
Astronomy
at
the
University
of
Wisconsin
after
receiving
his
B.A.
in
physics
from
Hanover
College.
He
had
postdoctoral
and
scientist
positions
at
Johns
Hopkins
University
and
the
University
of
California,
San
Diego,
joining
the
faculty
at
Notre
Dame
in
2005.
Prof.
Howk’s
research
is
focused
on
understanding
the
evolution
of
the
gaseous
components
of
galaxies
and
the
build
up
of
the
elements
since
the
Big
Bang.
His
recent
work
includes
using
the
light
elements
such
as
deuterium
and
lithium
to
constrain
the
conditions
of
the
Universe
just
after
the
Big
Bang.

Using
observations
from
the
Large
Binocular
Telescope,
the
Hubble
Space
Telescope,
and
others,
Prof.
Howk’s
group
is
attempting
to
piece
together
the
story
of
how
galaxies
acquire
their
gas
and
eject
some
gas
and
newly-­‐
created
metals
into
the
intergalactic
medium.
This
work
uses
spectroscopy
to
identify
the
gas
near
galaxies
and
spectroscopy
and
imaging
to
study
the
galaxies
themselves.
