NIBLES: an HI census of local SDSS galaxies
W. van Driel (Paris Observatory, GEPI), S. Schneider (UMASS), M., Lehnert (Paris Observatory, GEPI), and the NIBLES Consortium

TL;DR
NIBLES is a comprehensive survey using the Nancay Radio Telescope to measure the HI gas content and dynamics of 4,000 local SDSS galaxies, complementing other HI surveys and providing valuable data on galaxy properties.
Contribution
This study introduces a large, systematic HI census of local SDSS galaxies, filling gaps left by other surveys and enabling detailed analysis of galaxy gas content and dynamics.
Findings
Pilot survey of over 600 galaxies completed.
Estimated 40-45% detection rate with complementary surveys.
Provides a valuable dataset for understanding galaxy evolution.
Abstract
NIBLES is a Key Project proposed for the 100m-class Nancay Radio Telescope (NRT) in France. Its aim is a census of the HI gas content and dynamics of 4,000 Sloan Digital Sky Survey galaxies in the Local Volume (900<cz<12,000 km/s). The galaxies were selected based on their total stellar mass (absolute z-band magnitude Mz), and are distributed evenly over the entire range of Mz covered by local SDSS galaxies (-10 to -24 mag, for H0=70 km/s/Mpc). A pilot survey is being made of over 600 galaxies. NIBLES will be complementary to the ALFALFA and EBHIS blind HI surveys, which will detect a different ensemble of local galaxies, and which our pilot survey results indicate will detect about 40-45% of the NIBLES sample. NIBLES is an open collaboration and anyone interested in the science and willing to contribute to the project is welcome to join the score of NIBLErS.
