Background UGCA 86 is an irregular dwarf galaxy in the IC 342 / Maffei I group, just next to the Local Group. It was first mentioned by Zwicky (1968) as VII Zw 009, but not contained in his "Catalogue of Selected Compact Galaxies and of Post-eruptive Galaxies" (1971). It was independently rediscovered by Nilson (1974) and Rots (1979) as UGCA 86 and A 0355 resp. Rots found it by HI observations, and from peculiarities in the HI morphology and kinematics he suspected that it was interacting with IC 342. Thus, the tentatively interesting items: a starforming, low surface brightness dwarf galaxy in an interacting system (one of the nearest), triggered us to engage in more detailed studies. In a first step, we made detailed surface photometry in U, B and V (Richter et al. -

Science in the Urantia Papers
Science ¾ Scientific Validation of the UB z By Denver Pearson z By Phil Calabrese ¾ Seraphic Velocities ¾ Astronomy The Scientific Integrity of the Urantia Book by Denver Pearson As scientifically minded readers first peruse the Urantia Book, it soon occurs to them that many of its statements on the natural sciences conflict with currently held data and theories. In the minds of many this gives rise to doubts about the truthfulness of those statements. Wisdom would lead us to realize that nothing short of perfection is perfect, and anything touched by human hands has fingerprints. This should be our guiding thoughts as we contemplate the accuracy of the scientific content of the Urantia Papers. Several years ago, at the first scientific symposium, it was implied by one of the speakers that the revelation contains errors. This implication is alarming. More recently, at the second symposium held in Oklahoma, an interesting publication named "The Science Content of The Urantia Book" was made available (this document is obtainable from the Brotherhood of Man Library). In this publication is an article entitled "Time Bombs" in which the author suggests that the revelators planted certain inaccurate scientific statements in the book in order to prevent it from becoming a fetish. He states "...the revelators incorporated safeguards in the papers that would form The Urantia Book to diminish the tendency to regard it as an object of worship. What safeguards did they use? Suppose they decided to make sure that mortals reading it understood that some cosmological statements in the book would be found to be inaccurate". -

Star Formation History and Environment of the Dwarf Galaxy
Mon. Not. R. Astron. Soc. 000, 1–11 (XXX) Printed 12 November 2018 (MN LATEX style file v2.2) Star formation history and environment of the dwarf galaxy UGCA92⋆ Lidia Makarova1,2†, Dmitry Makarov1,2,3, Sergey Savchenko4 1Special Astrophysical Observatory, Nizhniy Arkhyz, Karachai-Cherkessia 369167, Russia 2Isaac Newton Institute of Chile, SAO Branch, Russia 3Universit´eLyon 1, Villeurbanne, F-69622, France; CRAL, Observatoire de Lyon, St. Genis Laval, F-69561, France 4Astronomical Institute, Saint-Petersburg State University, Saint-Petersburg, Russia Accepted XXX. Received XXX; in original form XXX ABSTRACT We present a quantitative star formation history of the nearby dwarf galaxy UGCA 92. This irregular dwarf is situated in the vicinity of the Local Group of galaxies in a zone of strong Galactic extinction (IC 342 group of galaxies). The galaxy was resolved into stars with HST/ACS including old red giant branch. We have constructed a model of the resolved stellar populations and measured the star formation rate and metallicity as function of time. The main star formation activity period occurredabout 8 – 14 Gyr ago. These stars are mostly metal-poor, with a mean metallicity [Fe/H] ∼−1.5– −2.0 dex. About 84 percent of the total stellar mass was formed during this event. There are also indications of recent star formation starting about 1.5 Gyr ago and continuing to the present. The star formation in this event shows moderate enhancement from ∼ 200 Myr to 300 Myr ago. It is very likely that the ongoing star formation period has higher metallicity of about −0.6 – −0.3 dex. -
The Triggering of Starbursts in Low-Mass Galaxies

We study the distribution and kinematics of the H I gas in the outer regions of 18 nearby starburst dwarf galaxies, that have accurate star-formation histories from HST observations of resolved stellar populations. We find that star- burst dwarfs show a variety of H I morphologies, ranging from heavily disturbed H I distributions with major asymmetries, long filaments, and/or H I-stellar offsets, to lop- sided H I distributions with minor asymmetries. We quantify the outer H I asymmetry for both our sample and a control sample of typical dwarf irregulars. Starburst dwarfs have more asymmetric outer H I morphologies than typical irregulars, suggesting that some external mechanism triggered the starburst. Moreover, galaxies hosting an old burst (&100 Myr) have more symmetric H I morphologies than galaxies hosting a young one (.100 Myr), indicating that the former ones probably had enough time to regularize their outer H I distribution since the onset of the burst. We also investigate the nearby environment of these starburst dwarfs and find that most of them (∼80%) have at least one potential perturber at a projected distance .200 kpc. -
An Observational Limit on the Dwarf Galaxy Population of the Local Group
An Observational Limit on the Dwarf Galaxy Population of the Local Group Alan B. Whiting1 Cerro Tololo Inter-American Observatory Casilla 603, La Serena, Chile [email protected] George K. T. Hau University of Durham Mike Irwin University of Cambridge Miguel Verdugo Institut f¨ur Astrophysik G¨ottingen, Germany ABSTRACT We present the results of an all-sky, deep optical survey for faint Local Group dwarf galaxies. Candidate objects were selected from the second Palomar survey (POSS-II) and ESO/SRC survey plates and follow-up observations performed to determine whether they were indeed overlooked members of the Local Group. arXiv:astro-ph/0610551v1 18 Oct 2006 Only two galaxies (Antlia and Cetus) were discovered this way out of 206 candi- dates. Based on internal and external comparisons, we estimate that our visual survey is more than 77% complete for objects larger than one arc minute in size and with a surface brightness greater than an extremely faint limit over the 72% of the sky not obstructed by the Milky Way. Our limit of sensitivity cannot be calculated exactly, but is certainly fainter than 25 magnitudes per square arc second in R, probably 25.5 and possibly approaching 26. We conclude that there are at most one or two Local Group dwarf galaxies fitting our observational cri- teria still undiscovered in the clear part of the sky, and roughly a dozen hidden behind the Milky Way. Our work places the “missing satellite problem” on a firm quantitative observational basis. We present detailed data on all our candidates, including surface brightness measurements. -

Appendices Due to Concerns Over the Quality of the Data Collected
APPENDIX A WSU 2014-19 STRATEGIC PLAN Appendix A: WSU Strategic Plan 2014-15 Strategic Plan 2014-2019 President Elson S. Floyd, Ph.D. Strategic Plan 2014-2019 Introduction The 2014-19 strategic plan builds on the previous five-year plan, recognizing the core values and broad mission of Washington State University. Goals and strategies were developed to achieve significant progress toward WSU’s aspiration of becoming one of the nation’s leading land-grant universities, preeminent in research and discovery, teaching, and engagement. The plan emphasizes the institution’s unique role as an accessible, approachable research institution that provides opportunities to an especially broad array of students while serving Washington state’s broad portfolio of social and economic needs. While providing exceptional leadership in traditional land-grant disciplines, Washington State University adds value as an integrative partner for problem solving due to its innovative focus on applications and its breadth of program excellence. The plan explicitly recognizes the dramatic changes in public funding that have occurred over the duration of the previous strategic plan, along with the need for greater institutional nimbleness, openness, and entrepreneurial activity that diversifies the University’s funding portfolio. In addition, the plan reaffirms WSU’s land-grant mission by focusing greater attention system-wide on increasing access to educational opportunity, responding to the needs of Washington state through research, instruction, and outreach, and contributing to economic development and public policy. While the new plan retains the four key themes of the previous plan, its two central foci include offering a truly transformative educational experience to undergraduate and graduate students and accelerating the development of a preeminent research portfolio. -
