XXIVe IAP COLLOQUIUM - FAR AWAY: LIGHT IN THE YOUNG UNIVERSE AT REDSHIFT   BEYOND 3   (comunicado por Gastão B. Lima Neto)) XXIVe IAP Colloquium   --  Paris, July 7-11 2008 Title: Far Away: Light in the young universe at redshift beyond 3 First Announcement. Deadline for poster and talk registration : March 15Deadline for registration : April 15 Information and registration form can be found at:http://www.iap.fr/col2008/ The birth of the first sources of light in the universe is a domain ofintense activity. The physical processes are investigated throughnumerical simulations and theoretical models and a more precise visionof the period of reionization and the end of the dark age is emerging.It is timely to bring together scientists working in this domain, torefine the predictions of models, and confront them with the growingbody of observations related to this early epoch. Sources at redshifts z=3 to 6, quasars and starburts, are currently studied routinely atall wavelengths. Faint objects are discovered and imaged with theSpace Telescope, while the large optical and infra-red ground-basedinstruments are obtaining their spectra. ALMA will soon discover a multitude of high-z sources, followed by the future Space telescopeand ELTs. The 21cm line will allow to follow the reionization of theuniverse directly, with LOFAR and the SKA precursors. The meeting willdiscuss the most recent observations in this high redshift range, andthe state of the art of models and numerical simulations. It willcover the following topics: -- The 21cm line during reionization-- Scenarii for reionization-- First stars and high-z quasars-- The star formation history in the early universe- - Absorption by the IGM-- GRBs as tracers of the remote universe -- Feedback and environment ----------------------------- Scientific Organising Committee R.

PESQUISA REALIZADA NO IF-UFRGS É DESTAQUE NA NASA (comunicado por Rodrigo Nemmen da Silva e Thaisa Storchi Bergmann) A new study using results from NASA's Chandra X-ray Observatory provides one of the best pieces of evidence yet that many supermassive black holes are spinning extremely rapidly. The whirling of these giant black holes drives powerful jets that pump huge amounts of energy into their environment and affects galaxy growth.

BANGLADESH: 100th MEMBRO DO IYA2009 (comunicado por Augusto Damineli) Caros astronomos a IAU comunica que o centésimo país -Bangladesh-  aderiu ao AnoInternacional da Astronomia. Desse modo, o IAY2009 já a maior redede divulgação científica mundial. PRESS RELEASE DA IAU: The International Year of Astronomy 2009 welcomes the 100th participating country The organisers of the International Year of Astronomy 2009 (IYA2009), the International Astronomical Union and UNESCO, welcomed this week the 100thparticipating country to the growing ranks of participating countries and organisations for this worldwide astronomy project. This milestone isreached only four weeks after the official Proclamation of IYA2009 by theUnited Nations. The latest country to join the International Year of Astronomy 2009initiative is the People's Republic of Bangladesh. This is a particularly welcome addition to the growing worldwide project since one of its aims is to promote astronomy and develop astronomical networks in developing countries. Mr. F. R. Sarker the General Secretary of the Bangladesh Astronomical Society is the Chair of the Bangladesh IYA2009 National Node and explains why he and his country are participating in the International Year of Astronomy 2009:"The IYA2009 is a historic event which will offer unique opportunities for the people of Bangladesh to learn more about the incredible developments in the field of astronomy." The International Year of Astronomy 2009 projects and activities aim to help millions of people worldwide to rediscover their place in the Universe through the day and night time sky, and thereby engage a personal sense of wonder and discovery. The International Year of Astronomy 2009 represents the largest coordinated effort of professional and non- professional astronomers in history for popularising astronomy. The President of the International Astronomical Union (IAU) Catherine Cesarsky says: "We are delighted that the International Year of Astronomy 2009 gives a chance tothe astronomers from the IAU member countries to reach out to the rest of the world and share the new knowledge and excitement of today's astronomy" Mr. F. R. Sarker adds: "Although being a developing country, Bangladesh has a large number of space enthusiasts, perhaps more than anywhere else in the world. The Bangladesh Astronomical Society aims to let 200,000 people observing the night sky through telescopes during 2009. On 22 July, 2009 a total solar eclipse will be visible on northern part of Bangladesh, this will be one of the most memorable celestial events in the history of the country. Our hope is that IYA2009 will enable Bangladesh to establish a large optical observatory in Chittagong to explore the mysteries of the Universe." The International Year of Astronomy 2009 will be a global celebration of astronomy and its contributions to society and culture, highlighted by the400th anniversary of the first use of an astronomical telescope by Galileo Galilei. In addition to the 100 countries already involved in the IYA2009,14 organisations are involved. Well over 140 countries and many organisations are expected to participate in the initiative in 2009. For more information about the International Year of Astronomy 2009 please visit the website at http://www.astronomy2009.org/ Notes for editors The vision of the IYA2009 is to help the citizens of the world rediscover their place in the Universe through the day and night time sky – and there by engage a personal sense of wonder and discovery. All humans should realize the impact of astronomy and basic sciences on our daily lives, and understand better how scientific knowledge can contribute to a more equitable and peaceful society. The aim of the IYA2009 is to stimulate worldwide interest, especially among young people, in astronomy and science under the central theme "The Universe, Yours to Discover". IYA2009 events and activities will promote a greater appreciation of the inspirational aspects of astronomy that embody an invaluable shared resource for all countries. The IYA2009 activities will take place at the global and regional levels, and especially at the national and local levels. National Nodes in each country have been formed to prepare activities for 2009. These Nodes establish collaborations between professional and amateur astronomers, science centres, educators and science communicators in preparing activities for 2009. The International Year of Astronomy (IYA2009) was proclaimed by the United Nations on 20 December 2007. The IAU is the international astronomical organisation that brings together almost 10,000 distinguished astronomers from all nations of the world. Its mission is to promote and safeguard the science of astronomy in all its aspects through international cooperation. The IAU also serves as the internationally recognised authority for assigning designations to celestial bodies and the surface features on them. Founded in 1919, the IAU is the world's largest professional body for astronomers. For more information, please contact: IYA2009 National Node Chair for the People's Republic of Bangladesh F. R.
