Group Identification in N-Body Simulations: SKID and DENMAX Versus Friends-of-Friends
M. Goetz, J. P. Huchra, R. H. Brandenberger
Three popular algorithms (FOF, DENMAX, and SKID) to identify halos in cosmological N-body simulations are compared with each other and with the predicted mass function from Press-S…
The Supergalactic Plane revisited with the Optical Redshift Survey
O. Lahav, B. X. Santiago, A. M. Webster +4
We re-examine the existence and extent of the planar structure in the local galaxy density field, the so-called Supergalactic Plane (SGP). This structure is studied here in three d…
A Cepheid Distance to the Fornax Cluster
B. F. Madore, W. L. Freedman, N. Silbermann +13
The Hubble Space Telescope is being used to measure accurate Cepheid distances to nearby galaxies with the ultimate aim of determining the Hubble constant, H_0. For the first time,…
The Hubble Space Telescope Key Project to Measure the Hubble Constant
Wendy L. Freedman, Jeremy R. Mould, Robert C. Kennicutt +1
A review of the Hubble Space Telescope H0 Key Project is given, as presented at the IAU Symposium 183 on "Cosmological Parameters" held in Kyoto, Japan in August, 1997. An outline…
