Unique Sky Survey Brings New Objects Into Focus 15 June 2009
Unique sky survey brings new objects into focus 15 June 2009 human intervention. The Palomar Transient Factory is a collaboration of scientists and engineers from institutions around the world, including the California Institute of Technology (Caltech); the University of California, Berkeley, and the Lawrence Berkeley National Laboratory (LBNL); Columbia University; Las Cumbres Observatory; the Weizmann Institute of Science in Israel; and Oxford University. During the PTF process, the automated wide-angle 48-inch Samuel Oschin Telescope at Caltech's Palomar Observatory scans the skies using a 100-megapixel camera. The flood of images, more than 100 gigabytes This is the Andromeda galaxy, as seen with the new every night, is then beamed off of the mountain via PTF camera on the Samuel Oschin Telescope at the High Performance Wireless Research and Palomar Observatory. This image covers 3 square Education Network¬-a high-speed microwave data degrees of sky, more than 15 times the size of the full connection to the Internet-and then to the LBNL's moon.

More computers using a type of artificial intelligence software sift through the results to identify the most An innovative sky survey has begun returning interesting "transient" sources-those that vary in images that will be used to detect unprecedented brightness or position. numbers of powerful cosmic explosions-called supernovae-in distant galaxies, and variable Within minutes of a candidate transient's discovery, brightness stars in our own Milky Way. -
A the Restless Universe. How the Periodic Table Got Built Up
A The Restless Universe. How the Periodic Table Got Built up This symposium will feature an Academy Lecture by Shrinivas Kulkarni, professor of Astronomy, California Institute of Technology, Pasadena, United States Date: Friday 24 May 2019, 7.00 p.m. – 8.30 p.m. Venue: Public Library Amsterdam, OBA Oosterdok, Theaterzaal OBA, Oosterdokskade 143, 1011 DL Amsterdam Abstract The Universe began only with hydrogen and helium. It is cosmic explosions which build up the periodic table! Astronomers have now identified several classes of cosmic explosions of which supernovae constitute the largest group. The Palomar Transient Factory was an innovative 2-telescope experiment, and its successor, the Zwicky Transient Factory (ZTF), is a high tech project with gigantic CCD cameras and sophisticated software system, and squarely aimed to systematically find "blips and booms in the middle of the night". Shrinivas Kulkarni will talk about the great returns and surprises from this project: super-luminous supernovae, new classes of transients, new light on progenitors of supernovae, detection of gamma-ray bursts by purely optical techniques and troves of pulsating stars and binary stars. ZTF is poised to become the stepping stone for the Large Synoptic Survey Telescope. Short biography S. R. Kulkarni is the George Ellery Hale Professor of Astronomy at the California Institute of Technology. He served as Executive Officer for Astronomy (1997-2000) and Director of Caltech Optical Observatories for the period 2006-2018. He was recognized by Cornell Uniersity with an AD White Professor-at-Large appointment. Kulkarni received an honorary doctorate from the Radboud University of Nijmegen, The Netherlands. -

As befits a topic dealing with change and variability, we ask you to shift your thinking somewhat for the next few days and accept the unique approach to scientific dialog that is a Scialog hallmark. It requires that you actively participate in the discussions by fearlessly brainstorming and saying what comes to mind, even if your thoughts on the topic under discussion may be considered unorthodox or highly speculative. The Scialog methodology also requires that you consider the novel ideas of others without summarily rejecting them, although constructive criticism is always appropriate. -

CALENDRICAL CALCULATIONS the Ultimate Edition an Invaluable
Cambridge University Press 978-1-107-05762-3 — Calendrical Calculations 4th Edition Frontmatter More Information CALENDRICAL CALCULATIONS The Ultimate Edition An invaluable resource for working programmers, as well as a fount of useful algorithmic tools for computer scientists, astronomers, and other calendar enthu- siasts, the Ultimate Edition updates and expands the previous edition to achieve more accurate results and present new calendar variants. The book now includes algorithmic descriptions of nearly forty calendars: the Gregorian, ISO, Icelandic, Egyptian, Armenian, Julian, Coptic, Ethiopic, Akan, Islamic (arithmetic and astro- nomical forms), Saudi Arabian, Persian (arithmetic and astronomical), Bahá’í (arithmetic and astronomical), French Revolutionary (arithmetic and astronomical), Babylonian, Hebrew (arithmetic and astronomical), Samaritan, Mayan (long count, haab, and tzolkin), Aztec (xihuitl and tonalpohualli), Balinese Pawukon, Chinese, Japanese, Korean, Vietnamese, Hindu (old arithmetic and medieval astronomical, both solar and lunisolar), and Tibetan Phug-lugs. It also includes information on major holidays and on different methods of keeping time. The necessary astronom- ical functions have been rewritten to produce more accurate results and to include calculations of moonrise and moonset. The authors frame the calendars of the world in a completely algorithmic form, allowing easy conversion among these calendars and the determination of secular and religious holidays. Lisp code for all the algorithms is available in machine- readable form. Edward M. Reingold is Professor of Computer Science at the Illinois Institute of Technology.
