The galaxy has a highly disturbed morphology indicative of a galaxy–galaxy merger remnant. The narrow blue filaments extend in straight shapes toward the south from the galaxy, and several bright blue knots are located at the southern ends of the filaments. The RC band absolute magnitudes, half light radii and estimated masses of the 6−7 bright knots are ∼ −12 −−13 mag, ∼ 200 − 300 pc and ∼ 10 M⊙, respectively. Long, narrow Hα-emitting filaments are connected at the south edge of the knots. The average color of the fireballs is B − RC ≈ 0.5, which is bluer than RB199 (B − R = 0.99), suggesting that most of the stars in the fireballs were formed within several times 108 yr. The narrow blue filaments exhibit almost no Hα emission. Strong Hα and UV emission appear in the bright knots. These characteristics indicate that star formation recently ceased in the blue filaments and now continues in the bright knots. The gas stripped by some mechanism from the disk of RB199 may be traveling in the intergalactic space, forming stars left along its trajectory.

    OCTOBER 2 0 0 6 �������������� http://www.universetoday.com �������������� TAMMY PLOTNER WITH JEFF BARBOUR 283 SUNDAY, OCTOBER 1 In 1897, the world’s largest refractor (40”) debuted at the University of Chica- go’s Yerkes Observatory. Also today in 1958, NASA was established by an act of Congress. More? In 1962, the 300-foot radio telescope of the National Ra- dio Astronomy Observatory (NRAO) went live at Green Bank, West Virginia. It held place as the world’s second largest radio scope until it collapsed in 1988. Tonight let’s visit with an old lunar favorite. Easily seen in binoculars, the hexagonal walled plain of Albategnius ap- pears near the terminator about one-third the way north of the south limb. Look north of Albategnius for even larger and more ancient Hipparchus giving an almost “figure 8” view in binoculars. Between Hipparchus and Albategnius to the east are mid-sized craters Halley and Hind. Note the curious ALBATEGNIUS AND HIPPARCHUS ON THE relationship between impact crater Klein on Albategnius’ southwestern wall and TERMINATOR CREDIT: ROGER WARNER that of crater Horrocks on the northeastern wall of Hipparchus. Now let’s power up and “crater hop”... Just northwest of Hipparchus’ wall are the beginnings of the Sinus Medii area. Look for the deep imprint of Seeliger - named for a Dutch astronomer. Due north of Hipparchus is Rhaeticus, and here’s where things really get interesting. If the terminator has progressed far enough, you might spot tiny Blagg and Bruce to its west, the rough location of the Surveyor 4 and Surveyor 6 landing area.

Greene Princeton University, Princeton, NJ, USA Jens Thomas Max Planck-Institute for Extraterrestrial Physics, Garching, Germany. Draft version June 21, 2021 ABSTRACT We present near-infrared observations of 35 of the most massive early-type galaxies in the local universe. The observations were made using the infrared channel of the Hubble Space Telescope (HST ) Wide Field Camera 3 (WFC3) in the F110W (1.1 µm) filter. We measured surface brightness profiles and elliptical isophotal fit parameters from the nuclear regions out to a radius of ∼10 kpc in most cases. We find that 37% (13) of the galaxies in our sample have isophotal position angle rotations greater than 20◦ over the radial range imaged by WFC3/IR, which is often due to the presence of neighbors or multiple nuclei. Most galaxies in our sample are significantly rounder near the center than in the outer regions. This sample contains six fast rotators and 28 slow rotators. We find that all fast rotators are either disky or show no measurable deviation from purely elliptical isophotes. Among slow rotators, significantly disky and boxy galaxies occur with nearly equal frequency.

  • Lensperfect A1689
    Draft Preprint typeset using LATEX style emulateapj v. 11/10/09 THE HIGHEST RESOLUTION MASS MAP OF GALAXY CLUSTER SUBSTRUCTURE TO DATE WITHOUT ASSUMING LIGHT TRACES MASS: LENSPERFECT ANALYSIS OF ABELL 1689 Dan Coe1, Narciso Ben´ıtez2, Tom Broadhurst3, Leonidas A. Moustakas1, and Holland Ford4 Draft ABSTRACT We present a strong lensing mass model of Abell 1689 which resolves substructures ∼ 25 kpc across (including about ten individual galaxy subhalos) within the central ∼ 400 kpc diameter. We achieve this resolution by perfectly reproducing the observed (strongly lensed) input positions of 168 multiple images of 55 knots residing within 135 images of 42 galaxies. Our model makes no assumptions about light tracing mass, yet we reproduce the brightest visible structures with some slight deviations. A1689 00 00 remains one of the strongest known lenses on the sky, with an Einstein radius of RE = 47:0 ± 1:2 +3 (143−4 kpc) for a lensed source at zs = 2. We find a single NFW or S´ersicprofile yields a good fit simultaneously (with only slight tension) to both our strong lensing (SL) mass model and published weak lensing (WL) measurements at larger radius (out to the virial radius). According to this NFW +0:5 15 −1 +0:4 15 −1 fit, A1689 has a mass of Mvir = 2:0−0:3 ×10 M h70 (M200 = 1:8−0:3 ×10 M h70 ) within the virial −1 +0:1 −1 +1:5 radius rvir = 3:0 ± 0:2 Mpc h70 (r200 = 2:4−0:2 Mpc h70 ), and a central concentration cvir = 11:5−1:4 (c200 = 9:2 ± 1:2).

  • 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.

  • ISO's Contribution to the Study of Clusters of Galaxies
    ISO's Contribution to the Study of Clusters of Galaxies ∗ Leo Metcalfe1 ([email protected]), Dario Fadda2, Andrea Biviano3 1XMM-Newton Science Operations Centre, European Space Agency, Villafranca del Castillo, PO Box 50727, 28080 Madrid, Spain 2Spitzer Science Center, California Institute of Technology, Mail code 220-6, 1200 East California Boulevard, Pasadena, CA 91125 3INAF - Osservatorio Astronomico di Trieste, via G.B. Tiepolo 11, 34131, Trieste, Italy Abstract. Starting with nearby galaxy clusters like Virgo and Coma, and continu- ing out to the furthest galaxy clusters for which ISO results have yet been published (z =0:56), we discuss the development of knowledge of the infrared and associated physical properties of galaxy clusters from early IRAS observations, through the “ISO-era” to the present, in order to explore the status of ISO’s contribution to this field. Relevant IRAS and ISO programmes are reviewed, addressing both the cluster galaxies and the still-very-limited evidence for an infrared-emitting intra-cluster medium. ISO made important advances in knowledge of both nearby and distant galaxy clusters, such as the discovery of a major cold dust component in Virgo and Coma cluster galaxies, the elaboration of the correlation between dust emission and Hubble- type, and the detection of numerous Luminous Infrared Galaxies (LIRGs) in several distant clusters. These and consequent achievements are underlined and described. We recall that, due to observing time constraints, ISO’s coverage of higher- redshift galaxy clusters to the depths required to detect and study statistically significant samples of cluster galaxies over a range of morphological types could not be comprehensive and systematic, and such systematic coverage of distant clusters will be an important achievement of the Spitzer Observatory.

  • Deep Surface Photometry of Edge-On Spirals in Abell Galaxy Clusters
    Astronomy & Astrophysics manuscript no. 9281 c ESO 2018 December 11, 2018 Deep surface photometry of edge-on spirals in Abell galaxy clusters: constraining environmental effects B. X. Santiago1 and T. B. Vale1 Instituto de F´ısica, Universidade Federal do Rio Grande do Sul, Av. Bento Gonc¸alves, 9500, CP 15051, Porto Alegre e-mail: [email protected] Received September 15, 1996; accepted March 16, 1997 ABSTRACT Context. There is a clear scarcity of structural parameters for stellar thick discs, especially for spiral galaxies located in high-density regions, such as galaxy clusters and compact groups. Aims. We have modelled the thin and thick discs of 4 edge-on spirals located in Abell clusters: NGC 705, ESO243G49, ESO187G19, LCSBS0496P. Deep I band images of NGC 705 were taken from the HST archive, whereas the remaining images were obtained with the Southern Telescope for Astrophysical Research (SOAR) in Gunn r filter. They reached surface brightness levels of µI ≃ 26.0 mag −2 −2 arcsec and µr ≃ 26.5 mag arcsec , respectively. Methods. Profiles were extracted from the deep images, in directions both parallel and perpendicular to the major axis. Profile fits were carried out at several positions, yielding horizontal and vertical scale parameters for both thin and thick disc components. Results. The extracted profiles and fitted disc parameters vary from galaxy to galaxy. Two galaxies have a horizontal profile with a strong down-turn at outer radii, preventing a simple exponential from fitting the entire range. For the 2 early-type spirals, the thick discs have larger scalelengths than the thin discs, whereas no trend is seen for the later types .

All the observed galaxies are within the redshift range 0.01 <z <> 0.15 and are constrained in position to Ä > -15°. We describe the observations and the reduction procedure. Contour maps of all the sources are presented. Comments on individual galaxies as well as morphological features are given. Subject headings: galaxies: jets — galaxies: structure — radio sources: galaxies I. INTRODUCTION nearby companions play in triggering the radio activity?

  • Büyük Patlama
    Kuark Bilgilerini Görmek İçin Tıkla Evren ve Büyük Patlama ya da Big Bang, evrenin yaklaşık 13,7 milyar yıl önce aşırı yoğun ve sıcak bir noktadan meydana geldiğini savunan evrenin evrimi kuramı ve geniş şekilde kabul gören[1] kozmolojik model.[2] İlk kez 1920’lerde Rus kozmolog ve matematikçi Alexander Friedmann ve Belçikalı fizikçi papaz Georges Lemaître [3] tarafından ortaya atılan, evrenin bir başlangıcı olduğunu varsayan bu teori, çeşitli kanıtlarla desteklendiğinden bilim insanları arasında, özellikle fizikçiler arasında geniş ölçüde[4] kabul görmüştür. Teorinin temel fikri, halen genişlemeye devam eden evrenin geçmişteki belirli bir zamanda sıcak ve yoğun bir başlangıç durumundan itibaren genişlemiş olduğudur. Georges Lemaître’in önceleri “ilk atom hipotezi” olarak adlandırdığı bu varsayım günümüzde “büyük patlama teorisi” adıyla yerleşmiş durumdadır. Modelin[2] iskeleti Einstein’ın genel görelilik kuramına dayanmakta olup, ilk Big Bang modeli Alexander Friedmann tarafından hazırlanmıştır. Model daha sonra George Gamow ve çalışma arkadaşları tarafından savunulmuş ve ilk nükleosentez olayı eklenmek suretiyle [5] geliştirilerek sunulmuştur.[1] 1929’da Edwin Hubble’ın uzak galaksilerdeki (galaksilerin ışığındaki) nispi kırmızıya kaymayı keşfinden sonra, bu gözlemi, çok uzak galaksilerin ve galaksi kümelerinin konumumuza oranla bir "görünür hız"a sahip olduklarını ortaya koyan bir kanıt olarak ele alındı. Bunlardan en yüksek "görünür hız"la hareket edenler en uzak olanlarıdır.[6] Galaksi kümeleri arasındaki uzaklık gitgide artmakta olduğuna göre, bunların hepsinin geçmişte bir arada olmaları gerekmektedir. Big Bang modeline göre, evren genişlemeden önceki bu ilk durumundayken aşırı derecede yoğun ve sıcak bir halde bulunuyordu. Bu ilk hale benzer koşullarda üretilen "parçacık hızlandırıcı"larla yapılan deney sonuçları teoriyi doğrulamaktadır. Fakat bu hızlandırıcılar, şimdiye dek yalnızca laboratuvar ortamındaki yüksek enerji sistemlerinde denenebilmiştir.
