... Astrophysics Group . ... Pulsars . ... Stars ? ... The array was designed to detect compact radio sources such as these by virtue of the fact that they would scintillate (twinkle) when observed from the Earth through the interplanetary medium ? ... One of Antony Hewish?s research students, Jocelyn Bell, was set the task of operating the telescope and inspecting the daily charts for the kind deflections in the trace which occurred when a scintillating source passed over the array. ...

... Posts tagged ?incompleteness? ... Comment . ... The notions of missing data are overall different between two communities. ... Astronomers?I?m not sure how they think but my impression so far is that a missing value in one attribute/variable from a object/observation/informant, all other attributes related to that object become useless because that object is not considered in scientific data analysis or model evaluation process. ... 2 Comments . ...

The ACA has been named the Morita Array after Professor Koh-ichiro Morita, who died in 2012 and was closely associated with the development of ALMA....

... NICS will be the only infrared instrument for the first light of the TNG; as a consequence, we decided to incorporate a sufficient degree of operation flexibility by providing the instrument with six different observing modes, three aimed at imaging and three at spectroscopy: . ... It will be possible to use the narrow band filters as order sorters; this will allow to perform high resolution long-slit spectroscopy in the wavelength ranges covered by the available narrow band filters. ...

... Gravitational wave search provides insights into galaxy evolution and mergers . ... galaxies . ... The Hubble Space Telescope found a galaxy that was completely formed within 480 million years of the Big Bang. How could gas and dust clouds condense into stars and organize themselves via gravity into an entire galaxy in less time than it takes the Milky Way to make two rotations? ... Galaxies like the Milky Way indeed could not have formed as a unit at such an early era after the Big Bang. ...

... The process of proposing for Hubble Space Telescope observing time has been revised, to make it simpler for proposers. We describe the simple, flexible, and robust prototype system created to handle proposal submission. ... Proposing for Hubble Space Telescope ( HST ) observing time proceeds in two phases: the scientific merits of the proposal are considered in Phase I; only accepted proposals enter Phase II, where the observations are described in complete detail. ...
