IC-342 IC-342 Is an Intermediate Spiral Galaxy in the Constellation Camelopardalis
MONTHLY OBSERVER’S CHALLENGE Las Vegas Astronomical Society Compiled by: Roger Ivester, Boiling Springs, North Carolina & Fred Rayworth, Las Vegas, Nevada With special assistance from: Rob Lambert, Las Vegas, Nevada November 2010 IC 342 (Caldwell 5) - Hidden Galaxy in Camelopardalis Introduction The purpose of the observer’s challenge is to encourage the pursuit of visual observing. It is open to everyone that is interested, and if you are able to contribute notes, drawings, or photographs, we will be happy to include them in our monthly summary. Observing is not only a pleasure, but an art. With the main focus of amateur astronomy on astrophotography, many times people tend to forget how it was in the days before cameras, clock drives, and GOTO. Astronomy depended on what was seen through the eyepiece. Not only did it satisfy an innate curiosity, but it allowed the first astronomers to discover the beauty and the wonderment of the night sky. Before photography, all observations depended on what the astronomer saw in the eyepiece, and how they recorded their observations. This was done through notes and drawings and that is the tradition we are stressing in the observers challenge. By combining our visual observations with our drawings, and sometimes, astrophotography (from those with the equipment and talent to do so), we get a unique understanding of what it is like to look through an eyepiece, and to see what is really there. The hope is that you will read through these notes and become inspired to take more time at the eyepiece studying each object, and looking for those subtle details that you might never have noticed before. -

Quantifying Satellites' Constellations Damages
S. Gallozzi et al., 2020 Concerns about Ground Based Astronomical Observations: Quantifying Satellites’ Constellations Damages in Astronomy 1 Concerns about ground-based astronomical observations: QUANTIFYING SATELLITES’CONSTELLATIONS DAMAGES STEFANO GALLOZZI1,D IEGO PARIS1,M ARCO SCARDIA2, AND DAVID DUBOIS3 [email protected], [email protected], INAF-Osservatorio Astronomico di Roma (INAF-OARm), v.

This work is aimed to raise awareness to the scientific astronomical community about the negative impact of satellites’ mega-constellations and estimate the loss of scientific contents expected for ground-based astro- nomical observations when all 50,000 satellites (and more) will be placed in LEO orbit. The first analysis regards the impact on professional astronomical images in optical windows. Then the study is expanded to other wavelengths and astronomical ground-based facilities (in radio and higher frequencies) to bet- ter understand which kind of effects are expected. Authors also try to perform a quantitative economic estimation related to the loss of value for public finances committed to the ground -based astronomical facilities harmed by satellites’ constellations. These evaluations are intended for general purposes and can be improved and better estimated; but in this first phase, they could be useful as evidentiary material to quantify the damage in subsequent legal actions against further satellite deployments. -

Dr. Jonathan Rall, Executive Secretary of PSS, noted that the agenda had changed slightly from what had been planned, so the session would begin with ethics training, followed by the Government Performance and Results Act (GPRA) Modernization Act (GPRA-MA) review and an update from the Analysis Group (AG) chairs. Dr. Janet Luhmann, PSS Chair, said that she hoped PSS would be able to have an in-person meeting early in 2014, probably in late February or early March, after the budget roll-out. In addition to the GPRAMA vote, this meeting was to include a discussion of the planned changes to NASA’s Planetary Science Division (PSD) Research and Analysis (R&A) program. Introductions Dr. Rall asked the attendees both at NASA and participating by teleconference to identify themselves. Ethics Training Ms. Katie Spear, representing NASA’s Office of General Counsel (OGC), presented the mandatory annual ethics training session to the Subcommittee members. -
Popular Names of Deep Sky (Galaxies,Nebulae and Clusters) Viciana’S List
POPULAR NAMES OF DEEP SKY (GALAXIES,NEBULAE AND CLUSTERS) VICIANA’S LIST 2ª version August 2014 There isn’t any astronomical guide or star chart without a list of popular names of deep sky objects. Given the huge amount of celestial bodies labeled only with a number, the popular names given to them serve as a friendly anchor in a broad and complicated science such as Astronomy The origin of these names is varied. Some of them come from mythology (Pleiades); others from their discoverer; some describe their shape or singularities; (for instance, a rotten egg, because of its odor); and others belong to a constellation (Great Orion Nebula); etc. The real popular names of celestial bodies are those that for some special characteristic, have been inspired by the imagination of astronomers and amateurs. The most complete list is proposed by SEDS (Students for the Exploration and Development of Space). Other sources that have been used to produce this illustrated dictionary are AstroSurf, Wikipedia, Astronomy Picture of the Day, Skymap computer program, Cartes du ciel and a large bibliography of THE NAMES OF THE UNIVERSE. If you know other name of popular deep sky objects and you think it is important to include them in the popular names’ list, please send it to [email protected] with at least three references from different websites. If you have a good photo of some of the deep sky objects, please send it with standard technical specifications and an optional comment. It will be published in the names of the Universe blog. It could also be included in the ILLUSTRATED DICTIONARY OF POPULAR NAMES OF DEEP SKY. -

TRANSIT the Newsletter Of
TRANSIT The Newsletter of 5 February 2006. Julian Day 2453772 Saturn images by Keith Johnson Editorial January 2006 Meeting – Members Night : An excellent contribution to Members Night from those members brave enough to face the as-ever critical Society membership. Michael Roe provided us with his detailed account of what the Apollo 11 Lunar team actually got up to on their short but heavily work-loaded visit to the Lunar surface. We all know they landed and took off again and in between said some memorable words and flew the flag, the usual inadequate media bites we have become used to. The talk was accompanied by Michael’s usual high standard of hand-drawn sketches. Again Rob Peeling surprised a lot of us by delving deeper into the NASA imaging archives than we usually surf for in our magazines and website trawling. I didn’t realize the Mars Rovers were taking images above the horizon, I was amazed at their sky astro- images including a possible meteor trail. We will all now look a bit deeper ourselves. John Crowther, our Society wordsmith, entertained us on the subject of “Time” and our use or abuse of it in the English language. Jurgen Schmoll, our professional perennial enthusiast showed us through his slide show how he got started in the business as a youngster. Although limited by his teenage purse he showed that a level of professio nalism could still be applied to astro-imaging with limited performance equipment and with bucketsful of enthusiasm. On top of all this he made us laugh with his humorous delivery, a welcome sound in the Parish Hall. -
Neural Methods for Effective, Efficient, and Exposure-Aware Information
Neural Methods for Effective, Efficient, and Exposure-Aware Information Retrieval Bhaskar Mitra A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy of University College London. Department of Computer Science University College London March 19, 2021 2 3 I, Bhaskar Mitra, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the work. Dedicated to Ma and Bapu Abstract Neural networks with deep architectures have demonstrated significant perfor- mance improvements in computer vision, speech recognition, and natural language processing. The challenges in information retrieval (IR), however, are different from these other application areas. A common form of IR involves ranking of documents—or short passages—in response to keyword-based queries. Effective IR systems must deal with query-document vocabulary mismatch problem, by mod- eling relationships between different query and document terms and how they indi- cate relevance. Models should also consider lexical matches when the query con- tains rare terms—such as a person’s name or a product model number—not seen during training, and to avoid retrieving semantically related but irrelevant results. In many real-life IR tasks, the retrieval involves extremely large collections—such as the document index of a commercial Web search engine—containing billions of documents. Efficient IR methods should take advantage of specialized IR data struc- tures, such as inverted index, to efficiently retrieve from large collections. Given an information need, the IR system also mediates how much exposure an information artifact receives by deciding whether it should be displayed, and where it should be positioned, among other results. -
