  • H-alpha as a luminosity class diagnostic in cool stars

    A new paper on research led by Jeff Jennings, an undergraduate research student of mine at the University of Colorado, is now in press with ApJ! We used echelle spectra of dwarf, giant, and supergiant K- and M-type stars taken using ARCES at the Apache Point Observatory 3.5m to examine the evolution of spectral features with luminosity class. As expected we […]

  • JWST, the UV Telescope

    The latest edition of the STScI Newsletter is now out and includes an article I wrote on studying star-forming galaxies at z>9 with JWST and what this means for our astronomy priorities in the meantime. JWST will be capable of observing photometry and spectra of astonishingly distant galaxies (z~10 and higher) that include massive star-forming galaxies and LGRB hosts. With its optimization for the IR […]

  • Physics GRE Scores of Astro Prize Fellows

    Recently myself, Rachel Bezanson, and Grant Tremblay conducted an information email questionnaire of astronomy prize postdoctoral fellows to gather data on the scores that they had received on the Physics GRE. We sent it to 271 people who had held U.S. prize fellowships (Hubble, Einstein, Sagan, Jansky, and/or NSF) between 2010-2015, and 149 people responded and reported Physics GRE scores. […]

  • New position at UW!

    Exciting news; as of today I’ve officially started a new position as an Assistant Professor in the astronomy department at the University of Washington! I’m so glad to be joining UW’s fantastic group of astronomers, building my own research group on all-things-massive-stars, and enjoying the beauty of the Pacific Northwest. It’s sure to be quite an adventure!

  • The Weirdest Stars in the Universe at STScI

    This past Tuesday I gave the STScI monthly public lecture in Baltimore, MD – thanks to everyone who braved the rain and thunderstorms to attend! The lecture was livestreamed online and is now available to watch on YouTube. This is one of my favorite public lecture topics, so check it out to learn more about enormous red supergiants, core-collapse supernovae (and their impostors), neutron […]
