We study the gas kinematics traced by the 21 cm emission of a sample of six H i-rich low surface brightness galaxies classified as ultra-diffuse galaxies (UDGs). Using the 3D kinematic modeling code 3DBarolo we derive robust circular velocities, reve...

The H i velocity function: a test of cosmology or baryon physics? (2019)
Journal Article
Chauhan, G., Lagos, C. D. P., Obreschkow, D., Power, C., Oman, K., & Elahi, P. J. (2019). The H i velocity function: a test of cosmology or baryon physics?. Monthly Notices of the Royal Astronomical Society, 488(4), 5898-5915. https://doi.org/10.1093/mnras/stz2069

Accurately predicting the shape of the Hi velocity function of galaxies is regarded widely as a fundamental test of any viable dark matter model. Straightforward analyses of cosmological N-body simulations imply that the ΛCDM model predicts an overab... Read More about The H i velocity function: a test of cosmology or baryon physics?.

We use integral-field spectroscopy from the SAMI Galaxy Survey to identify galaxies that show evidence of recent quenching of star formation. The galaxies exhibit strong Balmer absorption in the absence of ongoing star formation in more than 10% of t... Read More about The SAMI Galaxy Survey: Quenching of Star Formation in Clusters I.
