The results of medium resolution (R=600) spectrophotometry of 15 bright carbon stars of class N, obtained in the range of lambda:1 to 4.2 microns, are presented...
Warm IRAC [3.6] and [4.5] photometry is critical for understanding the cold population of brown dwarfs now being found, objects which have more in common with...
IRAM 30-meter millimeter follow-up of deep OSIRIS-GTC optical surveys
It is broadly accepted that CO is a reliable tracer of H2 in massive IR (L IR ≳ 10 9 L ⊙) galaxies, and that there are clear correlations between L IR and L' CO...
IRAS sources associated with small nebulae in dark clouds
CCD and near-IR broad and narrow-band images of HH 14 and 5 small nebula associated with IRAS sources of low luminosity in star forming regions are presented...
Iridium Metal in Melt Rock from the Chicxulub Impact Basin
We identified a ~4-micrometer-long, ~1 x 10^-10 g "nugget" of Ir metal in a melt rock sample from the Chicxulub impact basin. This particle, which consists of...
