    • Characteristic velocities of stripped-envelope core-collapse supernova cores 
      Maurer, J. I.; Mazzali, Paolo; Deng, J.; Filippenko, Alexei V.; Hamuy Wackenhut, Mario; Kirshner, Robert P.; Matheson, Thomas; Modjaz, Maryam; Pian, E.; Stritzinger, M.; Taubenberger, S.; Valenti, S. (2010)
      The velocity of the inner ejecta of stripped-envelope core-collapse supernovae (CC-SNe) is studied by means of an analysis of their nebular spectra. Stripped-envelope CC-SNe are the result of the explosion of bare cores ...
    • Detection of infall in the protostar B335 with ALMA 
      Evans II, Neal J.; Di Francesco, James; Lee, Jeong-Eun; Jørgensen, Jes K.; Choi, Minho; Myers, Philip C.; Mardones Pérez, Diego (The American Astronomical Society, 2015)
      Observations of the isolated globule B335 with ALMA have yielded absorption features against the continuum that are redshifted from the systemic velocity in both HCN and HCO+ lines. These features provide unambiguous ...
    • Herschel-HIFI view of mid-IR quiet massive protostellar objects 
      Herpin, F.; Chavarría, L.; Jacq, T.; Braine, J.; Tak, F. van der; Wyrowski, F.; Dishoeck, E. F. van; Baudry, A.; Bontemps, S.; Kristensen, L.; Schmalzl, M.; Mata, J. (EDP Sciences, 2016-03)
      Aims. We present Herschel/MEI observations of 14 water lines in a small sample of Galactic massive protostellar objects: NGC 6334I(N), DR21(OH), IRAS 16272-4837, and IRAS 05358+3543. Using water as a tracer of the structure ...
    • The outermost ejecta of Type Ia supernovae 
      Tanaka, Masaomi; Mazzali, Paolo; Benetti, Stefano; Nomoto, Ken’ichi; Elias-Rosa, Nancy; Kotak, Rubina; Pignata Libralato, Giuliano; Stanishev, Vallery; Hachinger, Stephan (UNIV CHICAGO PRESS, 2008-04-10)
      The properties of the highest velocity ejecta of normal Type Ia supernovae (SNe Ia) are studied via models of very early optical spectra of six SNe. At epochs earlier than 1 week before maximum, SNe with a rapidly evolving ...
    • SuperMALT: Physical and Chemical Properties of Massive and Dense Clumps 
      Neupane, Sudeep; Garay Brignardello, Guido; Contreras, Yanett (Cambridge University Press, 2017)
      The SuperMALT survey is observing 76 MALT90 clumps at different evolutionary stages (from pre-stellar or quiescent to HII) in high excitation molecular lines and key isotopomers using the Apex 12m telescope with an angular ...
