Absence of Radio Emission Reveals an Exceptionally Weak Explosion of the Putative Historical Supernova Pa 30

open access: yesThe Astrophysical Journal Letters
We present the first deep radio continuum observations of Pa 30, a nebula hosting a unique optical source driven by an ultrafast outflow with a velocity of 16,000 km s ^−1 .

Weak, extended water vapor emission in the Horsehead nebula

open access: yesAstronomy & Astrophysics
We analyzed archival Herschel observations of water vapor emission toward the Horsehead photon dominated region (PDR) along with supporting ground-based and airborne observations of CO isotopologs and fine structure lines of ionized and atomic carbon to ...
