Optically Unseen HI Detections towards the Virgo Cluster detected in the Arecibo Legacy Fast ALFA Survey
Brian R. Kent, Riccardo Giovanelli, Martha P. Haynes +8
We report the discovery by the Arecibo Legacy Fast ALFA (ALFALFA) survey of eight HI features not coincident with stellar counterparts in the Virgo Cluster region. All of the HI cl…
The Arecibo Galaxy Environment Survey: Precursor Observations of the NGC 628 group
R. Auld, R. F. Minchin, J. I. Davies +25
The Arecibo Galaxy Environment Survey (AGES) is one of several HI surveys utilising the new Arecibo L-band Feed Array (ALFA) fitted to the 305m radio telescope at Arecibo. The surv…
The Structure of Rapidly Rotating Late-Type Spiral Galaxies: I. Photometry, HI and Optical Kinematics
K. Spekkens, R. Giovanelli
We present I-band photometry, long-slit optical spectroscopy, and new aperture synthesis HI observations for eight late-type spirals with rotation velocities in the range 243 km/s…
The Arecibo Legacy Fast ALFA Survey: I. Science Goals, Survey Design and Strategy
Riccardo Giovanelli, Martha P. Haynes, Brian R. Kent
The recently initiated Arecibo Legacy Fast ALFA (ALFALFA) survey aims to map 7000 square degrees of the high galactic latitude sky visible from Arecibo, providing a HI line spectra…
The Cusp/Core Problem in Galactic Halos: Long-Slit Spectra for a Large Dwarf Galaxy Sample
Kristine Spekkens, Riccardo Giovanelli, Martha P. Haynes
We derive inner dark matter halo density profiles for a sample of 165 low-mass galaxies using rotation curves obtained from high-quality, long-slit optical spectra assuming minimal…
Inner Halo Shapes of Dwarf Galaxies: Resolving the Cusp/Core Problem
K. Spekkens, R. Giovanelli
We derive inner dark matter halo density profile slopes for a sample of 200 dwarf galaxies by inverting rotation curves obtained from high-quality, long-slit optical spectra. Using…
