The Survey of Ionized Gas of the Galaxy, Made with the Arecibo telescope (SIGGMA) provides a fully-sampled view of the radio recombination line (RRL) emission from the portion of the Galactic plane visible by Arecibo. Observations use the Arecibo L-b

It is known that among active galaxies (AG) with strong emission lines (UV-galaxies, Sy1 and Sy2, Markarian and Kazarian galaxies, radio-galaxies, QSOs host galaxies and so on) there is a large percentage of objects with double and multiple (or compl

Edwin E. Salpeter was a towering figure in twentieth-century astrophysics. Among his major scientific accomplishments is his 1955 paper ‘The luminosity function and stellar evolution’, where he first derived the empirical stellar initial mass fun

We present an atlas of Hubble Space Telescope images and ground-based, long-slit, narrowband spectra centered on the 6584 Angstrom line of [N ii] and the 5007 Angstrom line of [O iii]. The spectra were obtained for a variety of slit positions across

The positions of the IRAS counterparts to the 420 OH/IR stars in the Arecibo sky (0° < δ < +38°) are usually accurate to better than 10''. But every star has recently been observed by the Two Micron All Sky Survey (2MASS), which provides ~02 quali

We have combined two epochs of Hubble Space Telescope WFPC2 imaging data with ground-based expansion velocities to determine distances to three planetary nebulae (NGC 6578, NGC 6884, and IC 2448). We used two variants of the expansion parallax techni

Using complete redshift catalogs, we have compiled a list of galaxy pairs based solely on a pairs pro- jected separation, and velocity diUerence, *V. We have made high-velocity precision H I observations r p , of each galaxy in the sample and have re

We have used low‐resolution spectra from the International Ultraviolet Explorer (IUE) to look for periodicities in the ultraviolet flux from α Orionis. The total continuum flux for each observation was integrated, producing longwave (1900–3200 A
