Transcript

  1. About me • Grew up in Eagan, MN (Hooray snow

    and cold!) • UGrad: University of Puget Sound in Tacoma, WA (Hooray wet!) • Grad: UC Irvine, Irvine, CA (Hooray… warm?) • Postdoc: Yale University, New Haven, CT (Hooray Pizza!) • Postdoc & Sci Staff: STScI, Baltimore, MD (Hooray Neighborhoods!) • I enjoy hiking/backpacking, travel & nighttime (lucky to be an astronomer…), and nature of all sorts.
  2. (Scientific) Identities Topics • Observer ◦ Stellar spectroscopist ▪ Friend

    of M31 ◦ Optical imaging (imagineer?) ◦ HI survey dabbler • Theorist ◦ Near-field cosmologist ▪ Nature of Dark Matter (the really lowest density universe) ◦ Low mass galaxy simulations • Bayesian Statistician • Python Nerd Finding Local Dwarf Galaxies Reionization Characterizing Local Dwarf Galaxies SAGA Astropy

  4. You can do this in M31 too Collins, EJT, +

    2019 Gilbert, EJT, + 2018
  5. Finding Nearby Dwarfs: DELVE Main components: • WIDE: “Southern SDSS”

    (for dwarf galaxies) - talk to Yumi! • DEEP: Searching for “dwarfs of dwarfs” in the outer LG • MC: Magellanic Clouds (I’m less involved, but some of my best friends are Magellanic!) • I am “data processing coordinator” • Now with an STScI Remote Observing room! (RS443)
  6. Reionization: Tollerud & Peek + Leo T Also Leo T

    et al. are broadly intereting! Tollerud et al. 2x
  7. Satellites Around Galactic Analogs (SAGA) Survey Can we ask all

    the same questions, but for ~100 MW/M31 analogs at 20-40 Mpc? Beowulf Odyssey w/ Marla Geha, Risa Wechsler, Yao-Yuan Mao
  8. SAGA: My Current Focus - Rotation Curves and COS-SAGA Spatial

    -> Wavelength -> Rowland, EJT et al. 202x Tollerud or other et al. 202x
  9. Astropy • I am one of the founders and coordinators

    of Astropy. • None of the above was possible without it. • I can talk to you about/help you with Python and Open Development of software. • I can talk your ear off about the importance of sharing scientific software, giving credit for science s/w development. • I won’t right now.
