Introduction An important metric of the the success of ING telescopes is the count of papers published in refereed journals. Before reporting on the results of this exercise, it is worth commenting on and clarifying the selection process. One of the first decisions to make is that of choosing which journals to scan for ING articles. We have restricted the search to the core journals in which most of the ING papers are published, ie. the British journal MNRAS (including Letters), the American journals ApJ, ApJ Letters, ApJ Suppl, AJ and PASP, plus the European journal A&A (including Letters), although many other publications have appeared elsewhere, notably in workshop and conference proceedings and in PhD theses. We also searched Nature and Science as due to the perceived high impact of these journals. The bibliography for the years 2002 to 2011 were therefore compiled from only the core journals listed above. Online search engines were used to select papers containing a set of strings in the paper text: "William Herschel Telescope" OR "William Herschel Telescopes" OR "WHT" OR "Isaac Newton Telescope" OR "Isaac Newton Telescopes" OR "INT telescope" OR "Jacobus Kapteyn Telescope" OR "Jacobus Kapteyn Telescopes" OR "JKT" OR "ING Wide Field Survey" OR "INT Wide Field Survey" OR "La Palma archive" OR "ING archive” OR "Wide Field Survey" OR "Isaac Newton Group (ING) Archive" OR "WFS archive" OR "ING@WFS" OR "INT WFS" OR "Isaac Newton Group" OR "IPHAS OR La Palma" OR "Canary Islands" OR "WFC@INT" OR "INT/WFC" Papers were manually searched for proofs of having used ING data. To some extent this assessment is subjective since it is not always clear what constitutes making use of data from our telescopes. In principal and in general a paper should make direct use of observations in order to qualify. Papers which refer to data presented in earlier papers (derivative papers) are not counted. For every paper the following information was recorded: author list, year of publication, title, journal name, volume, first page, nationality of first author’s institution, telescope used and instrument. If the data came from one of the ING data archives then this was recorded in the instrument field as follows: “archive” refers to the ING archive, “WFS” refers to the INT Wide-Field Survey archive, and “IPHAS” refers to the archive of the INT/WFC photometric Hα survey of the northern Galactic plane. If the observations were obtained as part of an ING service or override proposal, then this is shown as “service” or “O/R” respectively in the instrument field. Appendix A shows the bibliography compiled this way. Papers are sorted by year and telescope and in alphabetical order of the first author. Nationalities appear in brackets and instruments in parentheses. What follows is an analysis of this bibliography. Note that if a paper makes use of more than one telescope we count that paper for each telescope. Similarly, if a paper makes use of more than one instrument, that paper is counted against each instrument. ING Technical Note No. 134 “ING Bibliography and Analysis 2002-2011” - Page 3 2.

(Mirametrics) What are Messier Objects? • Messier objects are a list of astronomical sources compiled by Charles Messier, an 18th and early 19th century astronomer. He created a list of distracting objects to avoid while comet hunting. This list now contains over 110 objects, many of which are the most famous astronomical bodies known. The list contains planetary nebula, star clusters, and other galaxies. - Bobby Martinez The Telescope The telescope used to take these images is an Astronomical Consultants and Equipment (ACE) 24- inch (0.61-meter) Ritchey-Chretien reflecting telescope. It has a focal ratio of F6.2 and is supported on a structure independent of the building that houses it. It is equipped with a Finger Lakes 1kx1k CCD camera cooled to -30o C at the Cassegrain focus. It is equipped with dual filter wheels, the first containing UBVRI scientific filters and the second RGBL color filters. Messier 1 Found 6,500 light years away in the constellation of Taurus, the Crab Nebula (known as M1) is a supernova remnant. The original supernova that formed the crab nebula was observed by Chinese, Japanese and Arab astronomers in 1054 AD as an incredibly bright “Guest star” which was visible for over twenty-two months. The supernova that produced the Crab Nebula is thought to have been an evolved star roughly ten times more massive than the Sun.

University of Cape Town Abstract Galaxy clusters can be sites of considerable dynamic activity due to intra-cluster and inter-cluster interactions. These interactions include cluster-cluster mergers which are accompanied by large release of energy observed via thermal 44 X-ray emission (LX ∼ 10 ergs/s). The work presented here focuses on clusters that exhibit extended (∼ 1 Mpc) diffuse radio sources (low surface brightness ∼ 1−0:1 µJy.arcsec−2 at 1.4 GHz) called radio relics and radio halos.

Received 2014 February 6; in original form 2013 May 31 ABSTRACT We carry out a systematic study of the X-ray emission from the active nuclei of the 0.02 <z< 0.7 2 Jy sample, using Chandra and XMM–Newton observations. We combine our results with those from mid-infrared, optical emission-line and radio observations, and add them to those of the 3CRR sources. We show that the low-excitation objects in our samples show signs of radiatively inefficient accretion. We study the effect of the jet-related emission on the various luminosities, confirming that it is the main source of soft X-ray emission for our sources.

Hewett2, M.J. Irwin2, G. Gilmore2, D.B. Zucker2, H.-W. Rix1, M. Fellhauer2, E.F. Bell1, E.V. Glushkova3 Draft version June 3, 2018 ABSTRACT We quantify the detectability of stellar Milky Way satellites in the Sloan Digital Sky Survey (SDSS) Data Release 5. We show that the effective search volumes for the recently discovered SDSS–satellites depend strongly on their luminosity, with their maximum distance, Dmax, substantially smaller than the Milky Way halo’s virial radius. Calculating the maximum accessible volume, Vmax, for all faint detected satellites, allows the calculation of the luminosity function for Milky Way satellite galaxies, accounting quantitatively for their detectability. We find that the number density of satellite galaxies continues to rise towards low luminosities, but may flatten at MV 5; within the uncertainties, the ∼− 0.1(MV +5) luminosity function can be described by a single power law dN/dMV = 10 10 , spanning × luminosities from MV = 2 all the way to the luminosity of the Large Magellanic Cloud. Comparing these results to several semi-analytic− galaxy formation models, we find that their predictions differ significantly from the data: either the shape of the luminosity function, or the surface brightness distributions of the models, do not match.

Abstract The understanding of the physics of relativistic jets from active galactic nuclei (AGN) is still incomplete. A way to understand the different features of the AGN jets is to study it broadband spectra. In general, within the limits of present observations, AGN jets are observed in radio-to-X-ray energy band and they exhibit various intrinsic features such as knots. Particularly, the blazar jets which are pointed towards the observer, are observed in radio-to-γ-ray and their radio maps exhibit internal jet structures. Moreover, the high energy emission from blazars show rapid variability. In this thesis, models have been developed to study the radiation emission processes from the knots of AGN jets as well as for blazar jets. A continuous injection plasma model is devel- oped to study the X-ray emission from the knots of sources 1136-135, 1150+497, 1354+195 and 3C 371. The knot dynamics is then studied within the framework of internal shock model. In such a scenario, knots are formed due to the collision of two successive matter blobs emitted sporadically from the central engine of AGN. Shocks, generated in such col- lisions, accelerate electrons to relativistic energies.
