DDO68 C: The Actual Appearance of a Ghost Satellite Dwarf through Adaptive Optics at the Large Binocular Telescope

Autor: Francesca Annibali, Enrico Pinna, Leslie K. Hunt, Diego Paris, Felice Cusano, Michele Bellazzini, John M. Cannon, Raffaele Pascale, Monica Tosi, Fabio Rossi

Publikováno v: The Astrophysical Journal Letters, Vol 942, Iss 1, p L23 (2023)

Through adaptive optics (AO) imaging with the SOUL+LUCI instrument at the Large Binocular Telescope we were able to resolve, for the first time, individual stars in the gas-rich galaxy DDO68 C. This system was already suggested to be interacting with

HST UV Spectroscopy of the Dwarf Starburst Galaxy Pox 186

Autor: Noah S. J. Rogers, Claudia M. Scarlata, Evan D. Skillman, Nathan R. Eggen, Anne E. Jaskot, Vihang Mehta, John M. Cannon

Publikováno v: The Astrophysical Journal, Vol 955, Iss 2, p 112 (2023)

Studying the galaxies responsible for reionization is often conducted through local reionization-era analogs; however, many of these local analogs are too massive to be representative of the low-mass star-forming galaxies that are thought to play a d

The Lyα Reference Sample. XIV. Lyα Imaging of 45 Low-redshift Star-forming Galaxies and Inferences on Global Emission

Publikováno v: The Astrophysical Journal Supplement Series, Vol 266, Iss 1, p 15 (2023)

We present Ly α imaging of 45 low-redshift star-forming galaxies observed with the Hubble Space Telescope. The galaxies have been selected to have moderate to high star formation rates (SFRs) using far-ultraviolet (FUV) luminosity and H α equivalen

A Search for Gas-Rich Dwarf Galaxies in the Local Universe with ALFALFA and the WIYN One Degree Imager

Autor: Katherine L. Rhode, Nicholas J. Smith, William F. Janesh, John J. Salzer, Elizabeth A. K. Adams, Martha P. Haynes, Steven Janowiecki, John M. Cannon

Publikováno v: The Astronomical Journal, Vol 166, Iss 3, p 113 (2023)

We present results from an optical search for Local Group dwarf galaxy candidates associated with the Ultra-Compact High Velocity Clouds (UCHVCs) discovered by the ALFALFA neutral hydrogen survey. The ALFALFA UCHVCs are isolated, compact H i clouds w

Catching Tidal Dwarf Galaxies at a Later Evolutionary Stage with ALFALFA

Autor: Laurin M. Gray, Katherine L. Rhode, Lukas Leisman, Pavel E. Mancera Piña, John M. Cannon, John J. Salzer, Lexi Gault, Jackson Fuson, Gyula I. G. Józsa, Elizabeth A. K. Adams, Nicholas J. Smith, Martha P. Haynes, Steven Janowiecki, Hannah J. Pagel

Publikováno v: The Astronomical Journal, Vol 165, Iss 5, p 197 (2023)

We present deep optical imaging and photometry of four objects classified as “Almost-Dark” galaxies in the Arecibo Legacy Fast Arecibo L-band Feed Array (ALFALFA) survey because of their gas-rich nature and extremely faint or missing optical emis

On the evolution of the size of Lyman alpha haloes across cosmic time: no change in the circumgalactic gas distribution when probed by line emission

Publikováno v: Monthly Notices of the Royal Astronomical Society, 522 (3)

Lyman α (Lyα) is now routinely used as a tool for studying high-redshift galaxies, and its resonant nature means it can trace neutral hydrogen around star-forming galaxies. Integral field spectrograph measurements of high-redshift Lyα emitters ind
