Here we report submillimetre (wavelength 870 micrometres) detections of 39 massive star-forming galaxies at z > 3, which are unseen in the spectral region from the deepest ultraviolet to the near-infrared. With a space density of about 2 × 10−5 per cubic megaparsec (two orders of ...
Massive black holes are believed to reside in the centers of many galaxies. Their seeds, 1000100 000 solar mass black holes are believed to have formed during the first epoch of star formation. Observations of X-ray binaries suggest that at least some intermediate mass black holes form at ...
When we talk about the “star-forming galaxies of the Local Group,” we are referring to the galaxies listed in Table 1, an updated version of Table 1 from Massey, 2003, Massey et al., 2007b. Table 1. Star-forming galaxies of the Local Group.a GalaxyTypelbMVE(B-V)bDist (Mpc)log...
During the Sun’s lifetime of 8 Gyr, massive stars will have enriched a few 104M⊙by many orders of magnitude if we assume an average mass of 20M⊙for each star. In that respect massive stars dominate the total energy output of galaxies as well as the energy balance in the ISM (see...
There are two fundamental reasons for studyingmassive starsamongst the star-forming galaxies of the Local Group. First, these galaxies allow us to perform tests of stellar evolutionary theory in a laboratory where primarily a single variable can be changed, namely the chemical composition of the sta...
Harvard astronomer Cara Battersby and two colleagues studied the formation, early evolution, and lifetimes of high-mass star-forming regions and their earliest evolutionary phases in dense, molecular regions. These clumps have densities of gas as high as ten million molecules per cubic centimeter (ten...

The masses of today's MBHs define surprisingly clear correlations with the properties of their host galaxies (luminosity, mass, and stellar velocity dispersion), suggesting a connected mechanism for assembling MBHs and forming galaxies. The evidence therefore favors a joint galaxy and MBH evolution. ...
