Rutgers' Black Hole Discovery: The First Galaxy
Without One Or The Smallest Black Hole Yet?
Rutgers astronomers have made a provocative
discovery -- the first galaxy without a supermassive
black hole (SBH) at its center or the smallest black
hole ever detected in the center of a galaxy. They
used the Hubble Space Telescope to observe the
galaxy ...

Study Stirs Old Debate About Galaxies
Using a technique that peeks over obscuring rings
of dust and gas and into the hearts of distant galaxies,
a researcher has found evidence suggesting that as
many as half of the bright, active galaxies known as
Seyfert 2 galaxies may have significantly less active
central black holes ...

Chandra Clinches Case For Unexpected Black
Hole Discovery
There's new evidence the universe is home to a type
of black hole that's not too large and not too small. As

"Great Show-Off" Black Hole Is Producing Massive
Shock Waves, Cornell Astronomer Reports
Something really shocking is going on in a microquasar,
or black hole, dubbed "Old Faithful," some 40,000 light
years from Earth. It seems to be behaving like a giant
particle collider, with massive shock waves generating
eruptions every 45 to 90 minutes. This is the second
time that Old Faithful, the first known microquasar in
our galaxy, the Milky Way, has been observed to be
acting strangely. ...

Which Came First: Black Hole Or Galaxy?
"The formation and evolution of galaxies are intimately
connected to the presence of a central massive black hole,"
said Douglas Richstone, leader of the research team and

and growth of black holes are the dominant sources of
heat and kinetic energy for star-forming gas in proto-
galaxies." ....
