Testing dark matter models and modified gravity theories with spatially resolved HI observations
Federico Lelli, Antonino Marasco, Timothy A. Davis +8
Understanding the nature of dark matter (DM) is one of the most pressing questions of modern physics. The flat rotation curves of galaxies, especially the extended HI rotation curv…
MIGHTEE-HI: The direct detection of neutral hydrogen in galaxies at
Matt J. Jarvis, Madalina N. Tudorache, I. Heywood +18
Atomic hydrogen constitutes the gas reservoir from which molecular gas and star formation in galaxies emerges. However, the weakness of the line means it has been difficult to dire…
MIGHTEE HI observations of low surface brightness and ultra-diffuse galaxies in the XMM-LSS field
Elizabeth A. K. Adams, Barbara Å iljeg, Anastasia Ponomareva +8
Untargeted neutral hydrogen (HI) surveys are well suited to identifying low surface brightness galaxies (LSBGs) that are gas rich, and they offer a complementary view to optically…
The long life of ultra diffuse galaxies inside low-density dark matter halos: the case of AGC 114905
Andrea Afruni, Federico Marinacci, Pavel E. Mancera Piña +1
It has long been known that, in the absence of a dark matter (DM) halo, galaxy discs tend to develop global gravitational instabilities that strongly modify their initial structure…
Photometry and kinematics of dwarf galaxies from the Apertif HI survey
Barbara Å iljeg, Elizabeth A. K. Adams, Filippo Fraternali +13
Context. Understanding the dwarf galaxy population in low density environments is crucial for testing the LCDM cosmological model. The increase in diversity towards low mass galaxi…
Exploring the nature of dark matter with the extreme galaxy AGC 114905
Pavel E. Mancera Piña, Giulia Golini, Ignacio Trujillo +1
AGC 114905 is a dwarf gas-rich ultra-diffuse galaxy seemingly in tension with the cold dark matter (CDM) model. Specifically, the galaxy appears to have an extremely low-density ha…
