    • The Anatomy of the Column Density Probability Distribution Function (N-PDF) 

      Chen, Hope; Burkhart, Blakesley; Goodman, Alyssa; Collins, David (American Astronomical Society, 2018-06-04)
      The column density probability distribution function (N-PDF) of Giant Molecular Clouds (GMCs) has been used as a diagnostic of star formation. Simulations and analytic predictions have suggested that the N-PDF is composed ...

    • The Interaction of Relativistic Spacecrafts with the Interstellar Medium 

      Hoang, Thiem; Lazarian, A.; Burkhart, Blakesley K.; Loeb, Abraham (American Astronomical Society, 2017)
      The Breakthrough Starshot initiative aims to launch a gram-scale spacecraft to a speed of v∼0.2c, capable of reaching the nearest star system, α Centauri, in about 20 years. However, a critical challenge for the initiative ...

    • Predicted Sizes of Pressure-Supported HI Clouds in the Outskirts of the Virgo Cluster 

      Burkhart, Blakesley K.; Loeb, Abraham (American Astronomical Society, 2016)
      Using data from the ALFALFA Arecibo HI survey of galaxies and the Virgo cluster X-ray pressure profiles from XMM-Newton, we investigate the possibility that starless dark HI clumps, also known as "dark galaxies", are ...

    • Unveiling the Role of the Magnetic Field at the Smallest Scales of Star Formation 

      Hull, Charles L. H.; Mocz, Philip; Burkhart, Blakesley K.; Goodman, Alyssa; Girart, Josep M.; Cortés, Paulo C.; Hernquist, Lars Eric; Springel, Volker; Li, Zhi-Yun; Lai, Shih-Ping (American Astronomical Society, 2017)
      We report Atacama Large Millimeter/submillimeter Array (ALMA) observations of polarized dust emission from the protostellar source Ser-emb 8 at a linear resolution of 140 au. Assuming models of dust-grain alignment hold, ...
