A Brief Summary of Black Holes: 

A Brief Summary of Black Holes Stellar-mass black holes The most massive stars end their lives in titanic explosions, leaving nothing behind but their ultra-dense collapsed cores. Mid-mass black holes A new class of recently-discovered black holes have masses on the order of hundreds or thousands of stars. Representations above are artists’ impressions, and not to scale. Supermassive black holes The 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.

X-ray Binary: Visible Light View: 

X-ray Binary: Visible Light View Many of the stars in our universe come in pairs. Ordinary stars orbiting around a black hole will appear to “wobble” in the sky. Sloan Digital Sky Survey

X-ray Binary: X-ray Light View: 

X-ray Binary: X-ray Light View More dramatically, matter being pulled off the orbiting star, into the accretion disk of the black hole, glows brightly in x-rays. NASA / SRON/MPE

Globular Cluster: Visible Light View: 

Globular Cluster: Visible Light View Globular clusters are large, dense clusters of stars. These stars are among the oldest stars in our universe. W. Keel (U. Alabama), et al.. 1.54-m Telescope, Chile

Globular Cluster: X-ray Light View: 

Globular Cluster: X-ray Light View Stars orbiting around black holes inside these ancient clusters are revealed by the x-ray glow of matter around them. NASA / CXC / CfA/J. Grindlay & C. Heinke

Milky Way Center: Visible Light View: 

Milky Way Center: Visible Light View 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. W. Keel (U. Alabama), et al.. 1.54-m Telescope, Chile

Milky Way Center: X-ray Light View: 

Milky Way Center: X-ray Light View Lurking within our galaxy’s hot, turbulent center are x-ray binaries, neutron stars, and even a supermassive black hole. NASA / U.Mass / D. Wang, et al.

Spiral Galaxy: Visible Light View: 

Spiral Galaxy: Visible Light View Like our own Milky Way, M74 is a majestic spiral. The swirling spiral arms house a menagerie of stars and stellar material. NOAO / AURA / NSF/ T. Boroson

Spiral Galaxy: X-ray Light View: 

Spiral Galaxy: X-ray Light View X-ray observations of strange new sources provide evidence for a new class of black holes, with the mass of 10,000 stars. NASA/CXC / U. Michigan / J. Liu et al.

Spiral Galaxy: Multi-wavelength View: 

Spiral Galaxy: Multi-wavelength View Combining x-ray and visible light observations can pinpoint the locations of black hole, providing a more complete picture. NASA / CXC / U. Michigan / J. Liu et al. NOAO / AURA / NSF / T. Boroson

Spiral Galaxies: An X-ray Gallery: 

Spiral Galaxies: An X-ray Gallery Thanks to the Chandra X-ray Observatory, these “mid-mass” black holes are becoming part of the story for all galaxies. NASA / CXC / SAO / R. DiStefano, et al.

Elliptical Galaxy: Visible and X-ray Views: 

Elliptical Galaxy: Visible and X-ray Views Indeed, most (if not all) galaxies are now thought to house a variety of black holes, ranging in mass from small to large. NASA / CXC / UVA / C. Sarazin, et al. Digital Sky Survey

Deep Field Galaxies: X-ray View: 

Deep Field Galaxies: X-ray View Looking out deep into space and back in time, we see supermassive black holes in the cores of the earliest galaxies. NASA / CXC / PSU /D. M. Alexander, F. E. Bauer, W. N. Brandt, et al.

Colliding Galaxies: A Black Hole Merger: 

If animation does not play automatically, download animation “Galaxy Merger and Chandra Data” from http://chandra.harvard.edu/photo/2002/0192/animations.html Direct Link: http://chandra.harvard.edu/photo/2002/0192/SimPlusData_small.mpg Animation must be in the same folder as presentation to run. Colliding Galaxies: A Black Hole Merger Actual observations provide evidence and data for computer simulations. What does it look like when black holes collide? NASA / CXC / MPE / S. Komossa, et al. J. Barnes (U.Hawaii) J. Hubbard (NRAO)

Centaurus A: Visible Light View: 

Centaurus A: Visible Light View Centaurus A is a nearby galaxy that is thought to be the result of a merger of two smaller galaxies. What’s behind the dust? M. Rejkuba (ESO-Garching) et al., ISAAC, VLT ANTU telescope, ESO Paranal Observatory

Centaurus A: X-ray Light View: 

Centaurus A: X-ray Light View 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! NASA / SAO / R. Kraft, et al.

Elliptical Galaxy: Visible and X-ray Views: 

Elliptical Galaxy: Visible and X-ray Views The elliptical galaxy M87 also houses a monster in its middle: the most massive black hole yet observed in our universe. NASA / CXC / M. Forman, et al. Palomar Observatory, Digitized Sky Survey

Black Holes Galore!: 

Black Holes Galore! From the formation of galaxies to the deaths of stars, black holes are an integral part of our universe’s history. NASA/CXC/SAO/H.Marshall et al. NASA/CXC/MIT/F.K.Baganoff et al. NASA/CXC/U.Amsterdam/S.Migliari et al. X-ray: NASA/CXC/MIT/UCSB/P.Ogle et al. Optical: NASA/STScI/A.Capetti et al NASA/UMD/A.Wilson et al.
