GALAXY STRUCTURAL PARAMETERS: STAR FORMATION RATE AND EVOLUTION WITH REDSHIFT M. TAKAMIYA1,2 Department of Astronomy and Astrophysics, University of Chicago, Chicago, IL 60637; and Gemini 8 m Telescopes Project, 670 North Aohoku Place, Hilo, HI 96720 Received 1998 August 4; accepted 1998 December 21 ABSTRACT The evolution of the structure of galaxies as a function of redshift is investigated using two param- eters: the metric radius of the galaxy(Rg) and the power at high spatial frequencies in the disk of the galaxy (s). A direct comparison is made between nearby (z D 0) and distant(0.2 [ z [ 1) galaxies by following a Ðxed range in rest frame wavelengths. The data of the nearby galaxies comprise 136 broad- band images at D4500A observed with the 0.9 m telescope at Kitt Peak National Observatory (23 galaxies) and selected from the catalog of digital images of Frei et al. (113 galaxies). The high-redshift sample comprises 94 galaxies selected from the Hubble Deep Field (HDF) observations with the Hubble Space Telescope using the Wide Field Planetary Camera 2 in four broad bands that range between D3000 and D9000A (Williams et al.). The radius is measured from the intensity proÐle of the galaxy using the formulation of Petrosian, and it is argued to be a metric radius that should not depend very strongly on the angular resolution and limiting surface brightness level of the imaging data. It is found that the metric radii of nearby and distant galaxies are comparable to each other.

  • A. L. Observing Programs Object Duplications
    A. L. OBSERVING PROGRAMS OBJECT DUPLICATIONS Compiled by Bill Warren Note: This report is limited to the following A. L. observing programs: Arp Peculiar Galaxies; Binocular Messier; Caldwell; Deep Sky Binocular; Galaxy Groups & Clusters; Globular Cluster; Herschel 400; Herschel II; Lunar; Messier; Open Cluster; Planetary Nebula; Universe Sampler; and Urban. It does not include the other A. L. observing programs, none of which contain duplicated objects. Like the A. L. itself, I’m using constellation names, not genitives (e.g., Orion, not Orionis) with double stars as an aid for beginners who might be referencing this. -Bill Warren Considerable duplication exists among the various A.L. observing programs. In fact, no less than 228 objects (8 lunar, 14 double stars and 206 deep-sky) appear in more than one program. For example, M42 is on the lists of the Messier, Binocular Messier, Universe Sampler and Urban Program. Duplication is important because, with certain exceptions noted below, if you observe an object once you can use that same observation in other A. L. programs in which that object appears. Of the 110 Messiers, 102 of them are also on the Binocular Messier list (18x50 version). To qualify for a Binocular Messier pin, you need only to find any 70 of them. Of course, they are duplicates only when you observe them in binocs; otherwise, they must be observed separately. Among its 100 targets, the Urban Program contains 41 Messiers, 14 Double Stars and 27 other deep-sky objects that appear on other lists. However, they are duplicates only if they are observed under light-polluted conditions; otherwise, they must be observed separately.

  • Making a Sky Atlas
    Appendix A Making a Sky Atlas Although a number of very advanced sky atlases are now available in print, none is likely to be ideal for any given task. Published atlases will probably have too few or too many guide stars, too few or too many deep-sky objects plotted in them, wrong- size charts, etc. I found that with MegaStar I could design and make, specifically for my survey, a “just right” personalized atlas. My atlas consists of 108 charts, each about twenty square degrees in size, with guide stars down to magnitude 8.9. I used only the northernmost 78 charts, since I observed the sky only down to –35°. On the charts I plotted only the objects I wanted to observe. In addition I made enlargements of small, overcrowded areas (“quad charts”) as well as separate large-scale charts for the Virgo Galaxy Cluster, the latter with guide stars down to magnitude 11.4. I put the charts in plastic sheet protectors in a three-ring binder, taking them out and plac- ing them on my telescope mount’s clipboard as needed. To find an object I would use the 35 mm finder (except in the Virgo Cluster, where I used the 60 mm as the finder) to point the ensemble of telescopes at the indicated spot among the guide stars. If the object was not seen in the 35 mm, as it usually was not, I would then look in the larger telescopes. If the object was not immediately visible even in the primary telescope – a not uncommon occur- rence due to inexact initial pointing – I would then scan around for it.

The survey, which includes 2352 nearby galaxies, reveals galaxy morphology only minimally affected by interstellar extinction. This paper presents an atlas and classifications of S4G galaxies in the Comprehensive de Vaucouleurs revised Hubble-Sandage (CVRHS) system. The CVRHS system follows the precepts of classical de Vaucouleurs (1959) morphology, modified to include recognition of other features such as inner, outer, and nuclear lenses, nuclear rings, bars, and disks, spheroidal galaxies, X patterns and box/peanut structures, OLR subclass outer rings and pseudorings, bar ansae and barlenses, parallel sequence late-types, thick disks, and embedded disks in 3D early-type systems. We show that our CVRHS classifications are internally consistent, and that nearly half of the S4G sample consists of extreme late-type systems (mostly bulgeless, pure disk galaxies) in the range Scd-Im.

  • 2021 Ride 'Em Cowboy
    The Eldorado Star Party 2021 Telescope Observing Club by Bill Flanagan Houston Astronomical Society Purpose and Rules Welcome to the Annual ESP Telescope Club! The main purpose of this club is to give you an opportunity to observe some of the showpiece objects of the fall season under the pristine skies of Southwest Texas. We have also included a few items on the observing lists that may challenge you to observe some fainter and more obscure objects that present themselves at their very best under the dark skies of the Eldorado Star Party. The rules are simple; just observe the required number of objects on the observing list while you are at the Eldorado Star Party to receive a club badge. Ride ‘Em Cowboy Saddle up and hold on tight, “Ride ‘Em Cowboy” is the Telescope Observing Club Program for ESP 2021. The program is a list of 29 objects located in the constellations Capricorn, Equuleus, Pegasus, Taurus, and Monoceros. Okay, I can hear the snarky comments now. “Real cowboys don’t ride a goat” and of course “Real cowboys don’t ride a unicorn!” But Capricorn is an awfully big goat in the southern sky and Monoceros, although a collection of dim stars, occupies 482 square degrees of the sky. Also, both of these constellations contain some of the toughest objects to observe on this year’s list. So hold the reins tight and don’t let these objects buck you off! You only need to observe 22 of the 29 objects on the list to qualify for the ESP Telescope Observing Club badge.
