    • No Hubble bubble in the local universe 
      Giovanelli, Ricardo; Dale, Daniel A.; Haynes, Martha P.; Hardy, Eduardo; Campusano, Luis E. (UNIV CHICAGO PRESS, 1999-11-01)
      Zehavi et al. have suggested that the Hubble flow within 70 h(-1) Mpc may be accelerated by the existence of a void centered on the Local Group. Its underdensity would be similar to 20%, which would result in a local Hubble ...
    • Searching for optical counterparts to ultra-compact high velocity clouds:Possible detection of a counterpart ... 
      Janesh, William; Rhode, Katherine L.; Salzer, John J.; Janowiecki, Steven; Adams, Elizabeth A. K.; Haynes, Martha P.; Giovanelli, Riccardo; Cannon, John M.; Muñoz Vidal, Ricardo Rodrigo (IOS Press, 2015)
      We report initial results from a campaign to obtain optical imaging of Ultra Compact High Velocity Clouds (UCHVCs) discovered by the Arecibo Legacy Fast ALFA (ALFALFA) HI survey. UCHVCs have properties consistent with their ...
    • Seeking the local convergence depth. II. Tully-Fisher observations of the clusters A114, A119, A194, A2295, ... 
      Dale, Daniel A.; Giovanelli, Riccardo; Haynes, Martha P.; Scodeggio, Marco; Hardy, Eduardo; Campusano, Luis E. (UNIV CHICAGO PRESS, 1998-02)
      We present Tully-Fisher (T-F) observations for nine rich Abell clusters of galaxies. This is the second such data installment of an all-sky survey of similar to 50 clusters in the redshift range 0.02 less than or similar ...
    • Seeking the local convergence depth. V. Tully-Fisher peculiar velocities for 52 Abell clusters 
      Dale, Daniel A.; Giovanelli, Riccardo; Haynes, Martha P.; Campusano, Luis E.; Hardy, Eduardo (UNIV CHICAGO PRESS, 1999-10)
      We have obtained I-band Tully-Fisher (T-F) measurements for 522 late-type galaxies in the fields of 52 rich Abell clusters distributed throughout the sky between similar to 50 and 200 h(-1) Mpc. Here we estimate corrections ...
    • Seeking the local convergence depth: The Abell cluster dipole flow to 200 h(-l) Mpc 
      Dale, Daniel A.; Giovanelli, Riccardo; Haynes, Martha P.; Campusano, Luis E.; Hardy, Eduardo; Borgani, Stefano (UNIV CHICAGO PRESS, 1999-01-01)
      We have obtained new Tully-Fisher (TF) peculiar velocity measurements for 52 Abell galaxy clusters distributed throughout the sky between similar to 50 and 200 h(-1) Mpc. The measurements are based on 1-band photometry and ...
    • Signatures of galaxy-cluster interactions: Spiral galaxy rotation curve asymmetry, shape, and extent 
      Dale, Daniel A.; Giovanelli, Riccardo; Haynes, Martha P.; Hardy, Eduardo; Campusano, Luis E. (UNIV CHICAGO PRESS, 2001-04)
      The environmental dependencies of the characteristics of spiral galaxy rotation curves are studied in this work. We use our large, homogeneously collected sample of 510 cluster spiral galaxy rotation curves to test the ...
