We investigate the dust associated with the supernova remnant (SNR) N49 in the Large Magellanic Cloud (LMC) as observed with the Herschel Space Observatory. N49 is unusually bright because of an interaction with a molecular cloud along its eastern edge. We have used PACS and SPIRE to measure the far IR flux densities of the entire SNR and of a bright region on the eastern edge of the SNR where the SNR shock is encountering the molecular cloud. ...

Evidence against the association of PSR B1706-44 with SNR G343.1-2.3 . ... Abstract An association between the supernova remnant SNR G343.1-2.3 and the pulsar PSR B1706-44 would imply a pulsar velocity greater than 1000 km/s. Observations of the pulsar scintillation made with the Parkes radio telescope at 20 and 70 cm indicate a velocity less than 50 km/s. This fact, coupled with statistical arguments and the morphology of both the SNR and the pulsar plerion, shows that the ...

... A Convex Hull Peeling Depth Approach to Nonparametric Massive Multivariate Data Analysis with Applications . Abstract: We explore the convex hull peeling process to develop empirical tools for statistical inferences on multivariate massive data. ... We define the convex hull peeling depth, which enables to order multivariate data. ... In addition to these empirical descriptive statistics, we find a few methodologies to separate multivariate outliers in massive data sets. ... Presentation [.pdf] . ...

The merging galaxy Arp 220 is the prototypical luminous infrared galaxy. ... In 1996, one of the then largest VLBI experiments was conducted on Arp 220, using the compact OH maser peak as a convenient phase reference. This permitted continuum imaging of the galaxy with high sensitivity, revealing the existence of roughly a dozen unresolved sub-mJy point sources scattered across the nuclear region of the galaxy. ... The nuclear region of Arp 220 imaged with continuum VLBI at 18 cm. ...
