The L_x-sigma Relation For Poor Groups of Galaxies
Marc E. Zimer, John S. Mulchaey, Ann I. Zabludoff
We use a sample of 20 poor groups of galaxies to study the low L_x tail of the L_x-sigma relationship. We have obtained redshifts for fainter members and deep X-ray imaging of thes…

A New Look at Poor Groups of Galaxies
Ann I. Zabludoff
We use a new fiber spectroscopic survey of 12 nearby, poor groups of galaxies to examine the dynamics and evolution of galaxies in these common, but poorly studied, environments. S…
