The effect of magnetic fields on star formation
Boss & Keiser examine how magnetic fields with varying initial conditions affect star formation.
A deep X-ray observation of Hickson Compact Group 62
Rafferty et al. study the effect of radio jets on the intracluster gas in Hickson Compact Group 62.
Sgr A*: A flickering black hole
Witzel et. al examine the statistical properties of the photometric variability of our Galaxy’s central black hole.
To be or not to be: central black holes in small stellar systems
Miller & Davies investigate whether central black holes should exist in low mass stellar systems such as globular clusters.
How to count stars you can’t see: the stellar IMF in distant galaxies
Van Dokkum & Conroy examane the variation of the stellar initial mass function by observing the integrated light from early-type galaxies.
Intermediate mass black holes: the elusive middle sibling
Strader et al. search for the elusive intermediate mass black holes in globular clusters.
The WISE way to deal with 2.7 million images: a public data release
The Wide-field Infrared Survey Explorer (WISE) data release promises many new and exciting discoveries!
Measuring the Black Hole Mass in Markarian 6 using Reverberation Mapping
Doroshenko et al. use extensive monitoring of the continuum and broad line region luminosities of Markarian 6 to measure the central black hole mass.
It takes two: the energy budget of common envelope evolution
Rebassa-Mansergas et al. investigate two long period post common envelope systems in order to place constraints on the energy budget for common envelope evolution.
Star formation in the Galactic Center
The Center of our Galaxy is one of the most extreme dynamical environments we can observe in detail because individual stars can actually be resolved using adaptive optics. Over time, monitoring individual stellar orbits has firmly established the presence of a supermassive black hole of about 4 x 106 M☉ (check out this video too). Further examination of these fast-moving stars’ properties (via infrared spectroscopy) revealed a surprising detail — many of these stars are young!
