2A Brief Summary of Black Holes
Stellar-mass black holesThe most massive stars
end their lives in titanic explosions, leaving
nothing behind but their ultra-dense collapsed
cores.
Mid-mass black holesA new class of
recently-discovered black holes have masses on
the order of hundreds or thousands of stars.
Supermassive black holesThe centers of galaxies
contain giant black holes, with the masses of
millions, even billions, of stars.
We cannot see black holes directly, but their
influence on the matter around them reveals
their presence.
Representations above are artists impressions,
and not to scale.
3X-ray Binary Visible Light View
Sloan Digital Sky Survey
Many of the stars in our universe come in pairs.
Ordinary stars orbiting around a black hole will
appear to wobble in the sky.
4X-ray Binary X-ray Light View
NASA / CXC / SAO
More dramatically, matter being pulled off the
orbiting star, into the accretion disk of the
black hole, glows brightly in x-rays.
5Globular Cluster Visible Light View
W. Keel (U. Alabama), et al.. 1.54-m Telescope,
Chile
Globular clusters are large, dense clusters of
stars. These stars are among the oldest stars in
our universe.
6Globular Cluster X-ray Light View
NASA / CXC / CfA/J. Grindlay C. Heinke
Stars orbiting around black holes inside these
ancient clusters are revealed by the x-ray glow
of matter around them.
7Milky Way Center Visible Light View
W. Keel (U. Alabama), et al.. 1.54-m Telescope,
Chile
The heart of our galaxy is a veritable soup of
stars, gas, and dust. On a clear night in a dark
sky, the view is breathtaking.
8Milky Way Center X-ray Light View
NASA / U.Mass / D. Wang, et al.
Lurking within our galaxys hot, turbulent center
are x-ray binaries, neutron stars, and even a
supermassive black hole.
9Spiral Galaxy Visible Light View
NOAO / AURA / NSF/ T. Boroson
Like our own Milky Way, M74 is a majestic spiral.
The swirling spiral arms house a menagerie of
stars and stellar material.
10Spiral Galaxy X-ray Light View
NASA/CXC / U. Michigan / J. Liu et al.
X-ray observations of strange new sources provide
evidence for a new class of black holes, with the
mass of 10,000 stars.
11Spiral Galaxy Multi-wavelength View
NASA / CXC / U. Michigan / J. Liu et al.NOAO /
AURA / NSF / T. Boroson
Combining x-ray and visible light observations
can pinpoint the locations of black hole,
providing a more complete picture.
12Spiral Galaxies An X-ray Gallery
NASA / CXC / SAO / R. DiStefano, et al.
Thanks to the Chandra X-ray Observatory, these
mid-mass black holes are becoming part of the
story for all galaxies.
13Elliptical Galaxy Visible and X-ray Views
Digital Sky Survey
NASA / CXC / UVA / C. Sarazin, et al.
Indeed, most (if not all) galaxies are now
thought to house a variety of black holes,
ranging in mass from small to large.
14Deep Field Galaxies X-ray View
NASA / CXC / PSU /D. M. Alexander, F. E. Bauer,
W. N. Brandt, et al.
Looking out deep into space and back in time, we
see supermassive black holes in the cores of the
earliest galaxies.

J. Barnes (U.Hawaii)J. Hubbard (NRAO)
Actual observations provide evidence and data for
computer simulations. What does it look like when
black holes collide?
16Centaurus A Visible Light View
M. Rejkuba (ESO-Garching) et al., ISAAC, VLTANTU
telescope, ESO Paranal Observatory
Centaurus A is a nearby galaxy that is thought to
be the result of a merger of two smaller
galaxies. Whats behind the dust?
17Centaurus A X-ray Light View
NASA / SAO / R. Kraft, et al.
A telltale sign of a black hole is a high-energy
jet blasting into space. This galaxy has a
supermassive black hole in its center!
18Elliptical Galaxy Visible and X-ray Views
Palomar Observatory, Digitized Sky Survey
NASA / CXC / M. Forman, et al.
The elliptical galaxy M87 also houses a monster
in its middle the most massive black hole yet
observed in our universe.
19Black Holes Galore!

From the formation of galaxies to the deaths of
stars, black holes are an integral part of our
universes history.
