Reynolds1, Jack Tueller2 Draft version November 25, 2018 ABSTRACT The 9-month SWIFT Burst Alert Telescope (BAT) catalog provides the first unbiased (NH < 1024 cm−2) look at local (<z>=0.03) AGN. In this paper, we present the collected X-ray properties (0.3 – 12 keV) for the 153 AGN detected. In addition, we examine the X-ray properties for a complete sample of non-beamed sources, above the Galactic plane (b 15◦). Of these, 45% are best fit by simple power law models while 55% require the more complex partial≥ covering model. One of our goals was to determine the fraction of “hidden” AGN, which we define as sources with scattering fractions 0.03 and ratios of soft to hard X-ray flux 0.04. We found that “hidden” AGN constitute a high percentage≤ of the sample (24%), proving that they≤ are a very significant portion of local AGN. Further, we find that the fraction of absorbed sources does increase at lower unabsorbed 2–10 keV luminosities, as well as accretion rates. This suggests that the unified model requires modification to include luminosity dependence, as suggested by models such as the ’receding torus’ model (Lawrence 1991). Some of the most interesting results for the BAT AGN sample involve the host galaxy properties. We found that 33% are hosted in peculiar/irregular galaxies and only 5/74 hosted in ellipticals. -

Received 2018 February 26; in original form 2017 December 14 ABSTRACT We present a statistical isophotal analysis of 138 early-type galaxies in the Antlia cluster, located at a distance of ∼ 35 Mpc. The observational material consists of CCD images of four 36 × 36 arcmin2 fields obtained with the MOSAIC II camera at the Blanco 4-m telescope at Cerro Tololo Interamerican Observatory. Our present work supersedes previous Antlia studies in the sense that the covered area is four times larger, the limiting magnitude is MB ∼−9.6 mag, and the surface photometry parameters of each galaxy are derived from Sersic´ model fits extrapolated to infinity. In a companion previous study we focused on the scaling relations obtained by means of surface photometry, and now we present the data, on which the previous paper is based, the parameters of the isophotal fits as well as an isophotal analysis. -

Integrated (C − T1) colours, T1 magnitudes, and effective radii have been measured for 93 galaxies (i.e. the largest galaxies sample in the Washington system till now) from the FS90 Antlia Group catalogue. Membership of 37 objects can be confirmed through new radial velocities and data collected from the literature. The resulting colour– magnitude diagram shows that early-type FS90 galaxies that are spectroscopically confirmed Antlia members or that were considered as definite members by FS90, follow a well-defined σ ∼ . -

Las mismas fueron descu- biertas hace poco m´as de una d´ecada, y presentan propiedades que podr´ıan relacionarlas tanto con los c´umulos globulares (CGs), como con galaxias de baja masa. Esto ha resultado en un abanico de hip´otesis sobre su origen, que incluyen ser los miembros m´as brillantes de los sistemas de CGs, los resultantes de la fusi´on de varios c´umulos estelares masivos durante eventos de formaci´on estelar particularmente intensos, o los remanentes de galaxias enanas nucleadas, desmembradas por las fuerzas tidales de galaxias vecinas masivas. -

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. -
