Optical and infrared spectrophotometry of 18 Markarian galaxies

Markarian Galaxies. I. the Optical Database and Atlas

A database for the entire Markarian catalog is presented that combines extensive new measurements of their optical parameters with a literature and database search. The measurements were made using images extracted from the STScI Digitized SkySurvey (DSS) of Fpg(red) and Jpg(blue) band photographic sky survey plates obtained by the Palomar and UK Schmidt telescopes. We provide accurate coordina...

Infrared spectrophotometry of enteric bacteria.

Infrared spectrophotometry is rapidly assuming an important place in the biological sciences. Its value derives from the fact that each organic compound has a characteristic and distinct infrared spectrum that can be used to identify it (Randall et al., 1949). The biologist working with cells or tissues is confronted by a highly complex mixture of substances. The infrared spectrum of a cell, th...

An Optical and Infrared Analysis of Blue Compact Dwarf Galaxies

An understanding of Blue Compact Dwarf galaxies (BCDs) and the processes occurring within their chemically un-evolved environments is fundamental in our understanding of the early universe. This thesis presents an investigation into their physical conditions, kinematics, chemical abundances and dust compositions. An optical integral field spectroscopy investigation of two perturbed BCDs, UM420 ...

Paraffinoma confirmed by infrared spectrophotometry.

Stis Ultraviolet/optical Spectroscopy of 'warm' Ultraluminous Infrared Galaxies

We present high spatial resolution ultraviolet and optical spectroscopy, obtained using the Space Telescope Imaging Spectrograph on board the Hubble Space Telescope, of nuclear structures within four 'warm' Ultraluminous Infrared Galaxies (ULIRGs). We find an AGN in at least three, and probably all four of our sample, hosted in a compact, optically luminous 'knot'. In three cases these knots we...
