Catching Tidal Dwarf Galaxies at a Later Evolutionary Stage with ALFALFA
Laurin M. Gray, Katherine L. Rhode, Lukas Leisman +11
We present deep optical imaging and photometry of four objects classified as "Almost-Dark" galaxies in the ALFALFA survey because of their gas-rich nature and extremely faint or mi…
Young, blue, and isolated stellar systems in the Virgo Cluster. I. 2-D Optical spectroscopy
M. Bellazzini, L. Magrini, M. G. Jones +20
We use panoramic optical spectroscopy obtained with MUSE@VLT to investigate the nature of five candidate extremely isolated low-mass star forming regions (Blue Candidates, BCs here…
Young, blue, and isolated stellar systems in the Virgo Cluster. II. A new class of stellar system
Michael G. Jones, David J. Sand, Michele Bellazzini +21
We discuss five blue stellar systems in the direction of the Virgo cluster, analogous to the enigmatic object SECCO 1 (AGC 226067). These objects were identified based on their opt…
The Turn-Down of the Baryonic Tully-Fisher Relation and Changing Baryon Fractions at Low Galaxy Masses
Kristen B. W. McQuinn, Elizabeth A. K. Adams, John M. Cannon +9
The ratio of baryonic-to-dark matter in present-day galaxies constrains galaxy formation theories and can be determined empirically via the baryonic Tully-Fisher relation (BTFR), w…
KK 242, a faint companion to the isolated Scd galaxy NGC 6503
Igor D. Karachentsev, John M. Cannon, Jackson Fuson +4
Using Hubble Space Telescope imaging of the resolved stellar population of KK~242 = NGC6503-d1 = PGC~4689184, we measure the distance to the galaxy to be Mpc and find…
AGC 226178 and NGVS 3543: Two deceptive dwarfs towards Virgo
Michael G. Jones, David J. Sand, Michele Bellazzini +21
The two sources AGC 226178 and NGVS 3543, an extremely faint, clumpy, blue stellar system and a low surface brightness dwarf spheroidal, are adjacent systems in the direction of th…
Galaxy Properties at the Faint End of the HI Mass Function
Kristen B. W. McQuinn, Anjana K. Telidevara, Jackson Fuson +9
The Survey of HI in Extremely Low-mass Dwarfs (SHIELD) includes a volumetrically complete sample of 82 gas-rich dwarfs with M_HI~<10^7.2 Msun selected from the ALFALFA survey. We a…
A Stringent Upper Limit on Dark Matter Self-Interaction Cross Section from Cluster Strong Lensing
Kevin E. Andrade, Jackson Fuson, Sophia Gad-Nasr +4
We analyze strongly lensed images in 8 galaxy clusters to measure their dark matter density profiles in the radial region between 10 kpc and 150 kpc, and use this to constrain the…
