Ultra-fast Outflows Help Monster Black Holes Shape Their Galaxies

A curious correlation between the mass of a galaxy’s central black hole and the velocity of stars in a vast, roughly spherical structure known as its bulge has puzzled astronomers for years. An international team led by Francesco Tombesi at NASA’s Goddard Space Flight Center in Greenbelt, Md., now has identified a new type of [continue reading]

In the Early Universe, Rapid Expansion or Something Very Weird

Without cosmic inflation, models explaining the early universe require “exotic physics,” like a speed of sound faster than the speed of light, UB researchers say The research, according to UB’s Kinney, “puts the idea of inflation on a much stronger footing” but, he says, other models may still be possible.

A little luck and a lot of hard work can really light up the sky. An ordinary-looking faint blue star (left) is actually a pair of white dwarfs that could someday light up the sky as a Type Ia supernova. We can’t see the second white dwarf, but we know of its presence, and the future [continue reading]

Dwarf galaxy questions current galaxy formation models

Dwarf galaxy questions current galaxy formation models

  Researcher from the Centro de Astrofísica da Universidade do Porto (Center for Astrophysics of the University of Porto) observed the dwarf galaxy I Zw 18, and found that much of what is known about galaxy formation and evolution might need substantial revision. CAUP Astronomer Polychronis Papaderos, along with his colleague Göran Östlin (Oskar Klein [continue reading]

World’s biggest astronomy project: ALMA telescope

   What better goal for the world’s biggest telescope than to probe details of how stars like our sun and planets like Earth came to be? Image Credit: ESO In the high desert of northern Chile, a new telescope with a revolutionary design is coming online – ready to probe deep into space. It will explore [continue reading]
