  • New paper: that’s no star…

    …it’s a photobomb by an AGN with a possible supermassive black hole binary! A new paper on research led by Trevor Dorn-Wallenstein, a graduate research student working with me at UW, has recently been published by ApJ and featured in a press release from the Chandra X-ray Observatory and the University of Washington. While searching for unusual massive stars in […]

  • Sloan Research Fellow in Physics!

    I’m very excited to have been named a 2017 Alfred P. Sloan Research Fellow in Physics! 126 fellowships were given this year to early-career faculty working in physics and seven other subfields, including several other astronomers and two other University of Washington faculty. It’s a real honor to be in the company of so many excellent scientists!

  • Two upcoming books on stars!

    I have two upcoming books on stars coming out later this year! Both will be published as part of the AAS-IOP Astronomy e-book collection. The first, “Astrophysics of Red Supergiants“, is a research monograph that’s meant to serve as a comprehensive reference for researchers from a broad range of subfields who are interested in red supergiants as extreme stages of stellar evolution, dust producers, supernova […]

  • 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 […]
