The effect of metallicity on the Cepheid P-L relation, from a Baade-Wesselink analysis of SMC Cepheids

Jesper Storm, Bruce W. Carney, Anne M. Fry

We present results based on a Baade-Wesselink analysis of Cepheids in the Small Magellanic Cloud. The Baade-Wesselink analysis provides individual luminosities for these metal-poor…

The peculiar motions of early-type galaxies in two distant regions - II. The spectroscopic data

Gary Wegner, Matthew Colless, R. P. Saglia +4

We present the spectroscopic data for the galaxies studied in the EFAR project, which is designed to measure the properties and peculiar motions of early-type galaxies in two dista…

The peculiar motions of early-type galaxies in two distant regions - V. The Mg-sigma relation, age and metallicity

Matthew Colless, David Burstein, Roger L. Davies +3

We examine the Mg-sigma relation for early-type galaxies in the EFAR sample and its dependence on cluster properties. A maximum likelihood fit gives global Mg-sigma relations of Mg…

On the Origins of Starburst and Post-Starburst Galaxies in Nearby Clusters

Nelson Caldwell, Jim Rose, Kristi Dendy

HST WFPC2 images in B (F450W) and I (F814W) have been obtained for three starburst (SB) and two post-starburst (PSB) galaxies in the Coma cluster, and for three such galaxies in th…

Discovery of a magnetar associated with the Soft Gamma Repeater SGR 1900+14

Chryssa Kouveliotou, Tod Strohmayer, Kevin Hurley +6

The soft-gamma repeater SGR 1900+14 became active again on June 1998 after a long period of quiescence; it remained at a low state of activity until August 1998, when it emitted a…

Cosmic Background Radiation Temperature Anisotropy: Position of First Doppler Peak

Paul H. Frampton, Y. Jack Ng, Ryan Rohm

The purpose of the Cosmic Background Radiation (CBR) experiments is to measure the temperature anisotropy via the autocorrelation function. The partial wave corresponding to…

Highest Energy Cosmic Rays

Paul H. Frampton

It is proposed that the highest energy eV cosmic ray primaries are protons, decay products of a long-lived progenitor whose high kinetic energy arises from decay of a…

The Smith Cloud: HI associated with the Sgr dwarf?

J. Bland-Hawthorn, S. Veilleux, G. Cecil +3

The Smith high velocity cloud (V(LSR) = 98 kms) has been observed at two locations in the emission lines [OIII]5007, [NII]6548 and H-alpha. Both the [NII] and H-alpha profiles show…
