Sandip Chakrabarti
Sandip Chakrabarti is an Indian astrophysicist. He developed a computer model to show how life on earth could have originated in outer space. Education He started his education in Lalit Mohan Shyam Mohini High School in Malda. After finishing his Bachelor of Science from Ramakrishna Mission Residential College, Narendrapur in Physics Honours in 1979 (and becoming topper of Calcutta University) he went to IIT, Kanpur to complete his M.Sc. Degree in Physics in 1981. He joined the Physics Dept. of the University of Chicago in 1981 to complete PhD work. Soon he completed a paper with Robert Geroch and X.B. Liang on a Theorem on "Time like Curves of limited acceleration in General Relativity", and under S. Chandrasekhar's supervision solved the Dirac equation for massive particles with spin in Kerr geometry. Subsequently, he concentrated on black hole astrophysics, received his Ph.D. in 1985 and went to Caltech as a R.C. Tolman Fellow. Major work in this period includes finding ...

Indian Centre For Space Physics
The Indian Centre for Space Physics (ICSP) is an Indian non-profit research organisation dedicated to carrying out advanced research in astronomy, astrophysics and space science. It is a sister institute of the University of Calcutta and the University of Gour Banga. It is located in the southern part of the city of Kolkata. It is shifting to its new Integrated campus on the Eastern metropolitan bypass 50 meters from Jyotirindra Nandy Metro station behind Metro Cash and Carry. Its Ionospheric and Earthquake Research Centre and optical observatory (IERCOO) where a 24-inch optical telescope (Vashista) has been installed. School and college students regularly carry out sky watching using its 10-inch telescope (Arundhati). The ground floor of the Integrated Campus will have an Astronomy and Space Museum which will be inaugurated very soon. Branches There are currently three branches at several places in West Bengal where people working in different fields of astrophysics: Malda (VLF ...

University Of Calcutta Alumni
A university () is an educational institution, institution of higher education, higher (or Tertiary education, tertiary) education and research which awards academic degrees in several Discipline (academia), academic disciplines. Universities typically offer both undergraduate education, undergraduate and postgraduate education, postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation ...

Black Holes
A black hole is a region of spacetime where gravity is so strong that nothing, including light or other electromagnetic waves, has enough energy to escape it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of no escape is called the event horizon. Although it has a great effect on the fate and circumstances of an object crossing it, it has no locally detectable features according to general relativity. In many ways, a black hole acts like an ideal black body, as it reflects no light. Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is of the order of billionths of a kelvin for stellar black holes, making it essentially impossible to observe directly. Objects whose gravitational fields are too strong for light to escape were first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gamma-ray Burst
In gamma-ray astronomy, gamma-ray bursts (GRBs) are immensely energetic explosions that have been observed in distant galaxies. They are the most energetic and luminous electromagnetic events since the Big Bang. Bursts can last from ten milliseconds to several hours. After an initial flash of gamma rays, a longer-lived "afterglow" is usually emitted at longer wavelengths (X-ray, ultraviolet, optical, infrared, microwave and radio). The intense radiation of most observed GRBs is thought to be released during a supernova or superluminous supernova as a high-mass star implodes to form a neutron star or a black hole. A subclass of GRBs appear to originate from the merger of binary neutron stars. The sources of most GRBs are billions of light years away from Earth, implying that the explosions are both extremely energetic (a typical burst releases as much energy in a few seconds as the Sun will in its entire 10-billion-year lifetime) and extremely rare (a few per galaxy per milli ...

Space
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. In classical physics, physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the ''Timaeus'' of Plato, or Socrates in his reflections on what the Greeks called ''khôra'' (i.e. "space"), or in the ''Physics'' of Aristotle (Book IV, Delta) in the definition of ''topos'' (i.e. place), or in the later "geometrical conception of place" as "spac ...
