WHAT ASTRONOMERS KNOW ABOUT YOUR GALAXY NGC 6925 Constellation Microscopium h m s Right Ascension 20 34 20.566 Declination −31° 58′ 51.20″ Distance 13.57 million light years Magnitude 11.3 Type SAbc NGC is an acronym for the New General Catalog, which was first published in 1888 and contains thousands of celestial objects. CONSTELLATION is the name of the constellation in which your galaxy can be found. You can use the planisphere in the Deluxe Package to locate the time of night and best days of the year to locate your constellation in the sky without a computer or telescope. You can also use the planisphere to learn all your constellations. RIGHT ASCENSION is the celesital equivalent of longitude and divides the sky into 24 hours of celestial longitude. DECLINATION is the celestial latitude. A negative number means the object is below the celestial equator. With the Right Ascension and Declination coordinates, any observatory or large backyard telescope can locate your galaxy in the night sky. DISTANCE is the estimated distance of your galaxy from Earth. MAGNITUDE relates to the brightness of a galaxy. The bigger the number, the fainter the object. The human eye cannot see objects fainter than Magnitude 6. The Andromeda Galaxy is the only galaxy visible to the naked eye under very dark conditions (miles away from city lights). TYPE denotes the kind of galaxy it is. The general classifications are: S = Spiral Galaxy, SB = barred spiral galaxies, E = Elliptical Galaxy, Irr = Irregular Galaxy; from these there are many subtypes. Your galaxy is a SAbc, an intermediate spiral galaxy that is in between the classifications of a spiral galaxy and a barred spiral galaxy. Visit nameagalaxy.com to learn more about galaxy types. .

Observational Studies of the Galaxy Peculiar Velocity Field
OBSERVATIONAL STUDIES OF THE GALAXY PECULIAR VELOCITY FIELD by Philip Andrew James Astrophysics Group Blackett Laboratory Imperial College of Science, Technology and Medicine London SW7 2BZ A thesis submitted for the degree of Doctor of Philosophy of the University of London and for the Diploma of Imperial College November 1988 1 ABSTRACT This thesis describes two observational studies of the peculiar velocity field of galaxies over scales of 50-100 Jr1 Mpc, and the consequences of these measurements for cosmological theories. An introduction is given to observational cosmology, emphasising the crucial questions of the nature of the dark matter and the formation of structure. The principal cosmological models are discussed, and the role of observations in developing these models is stressed. Consideration is given to those observations that are likely to prove good discriminators between the competing models, particular emphasis being given to studies of the coherent velocities of samples of galaxies. The first new study presented here uses optical photometry and redshifts, from the literature, for First Ranked Cluster Galaxies (FRCG’s). These galaxies are excellent standard candles, and thus ideal for peculiar velocity studies. A simple one dimensional analysis detects no relative motion between the Local Group of galaxies and 60 FRCG’s with redshifts of up to 15000 kms-1. This is shown to imply a streaming motion of the cluster galaxies of at least 600 kms_1 relative to the CBR. The second observational study is a reanalysis of the Rubin et al. (1976a,b) sample of Sc galaxies. Near-IR photometry is used in our reanalysis to minimise the effects of extinction and to facilitate the use of luminosity indicators in reducing the effects of selection biases.

On the Relation Between Circular Velocity and Central Velocity Dispersion in High and Low Surface Brightness Galaxies1 A
The Astrophysical Journal, 631:785–791, 2005 October 1 A # 2005. The American Astronomical Society. All rights reserved. Printed in U.S.A. ON THE RELATION BETWEEN CIRCULAR VELOCITY AND CENTRAL VELOCITY DISPERSION IN HIGH AND LOW SURFACE BRIGHTNESS GALAXIES1 A. Pizzella,2 E. M. Corsini,2 E. Dalla Bonta`,2 M. Sarzi,3 L. Coccato,2 and F. Bertola2 Received 2005 January 5; accepted 2005 March 24 ABSTRACT In order to investigate the correlation between the circular velocity Vc and the central velocity dispersion of the spheroidal component c , we analyzed these quantities for a sample of 40 high surface brightness (HSB) disk galaxies, eight giant low surface brightness (LSB) spiral galaxies, and 24 elliptical galaxies characterized by flat À1 À1 rotation curves. Galaxies have been selected to have a velocity gradient 2kms kpc for R 0:35R25.Weused these data to better define the previous Vc-c correlation for spiral galaxies (which turned out to be HSB) and elliptical galaxies, especially at the lower end of the c values. We find that the Vc-c relation is described by a linear À1 law out to velocity dispersions as low as c 50 km s , while in previous works a power law was adopted for À1 galaxies with c > 80 km s . Elliptical galaxies with Vc based on dynamical models or directly derived from the H i rotation curves follow the same relation as the HSB galaxies in the Vc-c plane. On the other hand, the LSB galaxies follow a different relation, since most of them show either higher Vc or lower c with respect to the HSB galaxies.

Emissão Infra - Vermelha De Galáxias Iras
UNIVERSIDADE FEDERAL DO RIO GRANDE DO SUL INSTITUTO DE FÍSICA EMISSÃO INFRA - VERMELHA DE GALÁXIAS IRAS Charles José Bonatto Tese realizada sob a orientação da Dra. Miriani G. Pastoriza e apresentada ao Instituto de Física da UFRGS, em preenchi- mento parcial dos requisitos para a obtenção do título de Doutor em Física. Porto Alegre 1992 *Trabalho financiado pelo Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq). Aos meus pais, irmãos e cunhados. Agradecimentos À Miriani Pastoriza por sua orientação e confiança; À Sebastian Lípari por ter fornecido as observações de CASLEO; A todo o pessoal do Departamento de Astronomia, pelos bons momentos que têm sido proporcionados; Ao pessoal da Biblioteca, em especial à Zuleika e à Ana; A todas as pessoas que direta ou indiretamente contribuíram para este trabalho; Ao CNPq, pelo financiamento deste trabalho; À FAPERGS, pelo apoio financeiro em um dos turnos em Tololo. Resumo Galáxias ativas emitem fortemente no infra-vermelho. Grãos de poeira, aquecidos por fótons Ultra-Violeta e ópticos absorvem estes fótons e os re-emitem no infra-vermelho. Atualmente, esta é a interpretação mais provável para esta emissão no infra-vermelho. Neste trabalho, desenvolvemos um modelo para a emissão e distribuição espacial dos graõs de poeira, incluindo a contribuição de uma lei-de-potência. Usamos galáxias com observações no óptico e no infra-vermelho, separando-as em Seyfert tipo 1 e 2, para analisar as relações entre luminosidades de linhas de emissão no óptico e a luminosidade no infra-vermelho (LIR). Contando o número de galáxias com L r.. dentro de um determinado intervalo, mostramos que as distribuições de LIR de Seyferts tipo 1 e 2 são quase idênticas.

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 COLOUR of CREATION observing and astrophotography targets “at a glance” guide. (Naked eye, binoculars, small and “monster” scopes) Dear fellow amateur astronomer. Please note - this is a work in progress – compiled from several sources - and undoubtedly WILL contain inaccuracies. It would therefor be HIGHLY appreciated if readers would be so kind as to forward ANY corrections and/ or additions (as the document is still obviously incomplete) to: [email protected]. The document will be updated/ revised/ expanded* on a regular basis, replacing the existing document on the ASSA Pretoria website, as well as on the website: coloursofcreation.co.za . This is by no means intended to be a complete nor an exhaustive listing, but rather an “at a glance guide” (2nd column), that will hopefully assist in choosing or eliminating certain objects in a specific constellation for further research, to determine suitability for observation or astrophotography.

Only 31% of SNe were detected. We characterize the SN radio lightcurves near the peak using a two-parameter model, with tpk being the time to rise to a peak and Lpk the spectral luminosity at that peak. Over all SNe in 1:7±0:9 25:5±1:6 −1 −1 our sample at D < 100 Mpc, we find that tpk = 10 d, and that Lpk = 10 erg s Hz , 25:5 −1 −1 and therefore that generally, 50% of SNe will have Lpk < 10 erg s Hz . These Lpk values are ∼30 times lower than those for only detected SNe.
