Observations of SOHO-detected comet 322P from the ground and from Spitzer suggest it may be of asteroidal origin. If so, it has the shortest perihelion distance of any known asteroid.
Rachel C. Wolf et al 2016 ApJ 821 115
Spectroscopy of 345 Type Ia supernovae is used to study the correlations between various properties of the supernovae and the properties of their host galaxies.
Mina Pak et al 2016 AJ 151 141
A morphological study of the dwarf lenticular galaxy MCG+08-22-082 reveals two cores of 10^6 solar masses and ongoing star formation. This may be an intermediate merger stage of two disk galaxies.
Catherine Zucker et al 2016 ApJ 821 113
Wide-field Infrared Survey Explorer (WISE) data from 163 compact galaxy groups confirms bimodal behavior: these galaxies are either quiescent with low star formation rates, or they are prolifically forming stars.
A. Kashlinsky 2016 ApJ 823 L25
If LIGO-type primordial black holes make up the bulk or all of dark matter, this would increase the abundance of early collapsed dark-matter halos, suitable for producing the first generation of stars.
Christopher M. Faesi et al 2016 ApJ 821 125
Submillimeter-Array observations of giant molecular clouds (GMCs) in NGC 300 indicate that these star-forming regions are similar to GMCs in the disks of the Milky Way and other nearby spiral galaxies.
