Recent Work:

 
  • We have presented a poster of new results from our deep imaging survey of galaxy clusters at the Carnegie Symposium III.  The actual poster is available here Be warned that the poster is 10 MB in size, and will need to be rescaled to print normally.

    The conference proceeding related to this poster can be found here


  • Along with my long-time collaborators Robin Ciardullo, George Jacoby, & Pat Durrell, we have undertaken a dynamical study of one of our nearest extragalactic neighbors: M33.  Planeatry nebulae make good dynamical probes, and we can use them to place limits on any "maximal disks" found in M33.  Pat Durell presented a poster of our initial results, which can be found here.


  • Along with many collaborators, I have studied the galactic planetary nebulae SBS1150+599A.  The paper has been accepted to the A.J., and is available here.  A small mini-talk with the results is here

  •  
  • Along with my long-time collaborators Robin Ciardullo, George Jacoby, & Pat Durrell, we have continued our use of extragalactic planetary nebulae as distance indicators.  We have distances for five more spiral galaxies that also have high quality Cepheid distances, which allows us to compare the differences between both distance indicators.  The paper has been accepted to the Ap. J., and is available here.

  •  
  • I and my colleagues at the PoPSICL project have published our first results on a search in two galaxy clusters for intracluster light. We find that there is significant evidence for intracluster light in both clusters, and that Abell 1413 may have the most elliptical ICL yet discovered. The paper has been accepted to the Ap. J., and is available here.

  •  
  • I have written a review paper on intracluster planetary nebulae. The paper is available here.

  •  
  • We have started a survey for intra-group planetary nebulae in the M81 group of galaxies. This group is known to be strongly interacting (see the beautiful HI map of Yun, Ho and Lo displayed here. See also here). We found relatively few intra-group PN, but our survey is continuing. Our IAU 209 conference proceeding on the subject is here. (68k, Postscript)

  •  
  • We have completed a radial velocity survey for planetary nebulae in the famous interacting galaxy M51. We have found a complex velocity distribution in the data, especially in a tidal-tail structure. With the excellent N-body models by Chris Mihos, we can easily explain the features in the data without fine tuning. An MPEG movie that shows our best-fitting model of the interaction can be seen here The paper has been accepted to the Ap. J., and is available here
