Supercomputer Simulation to Investigate Black Hole and Galaxy Coevolution: Quasar Fueling

August 18, 2021August 18, 2021 Pooja Kashyap

Big question regarding the formation of black holes and how they grow under different regimes have always been the holy grail for astrophysicists. Our galaxy hovers around a massive black hole which, under normal circumstances, is surrounded by spinning gases. Not much is known about these gases, however, some shine brightly, with an unceasing supply of fuel. While others go to a state of temporary dormancy and erupts again later with an influx of gases.

X-ray Emission from Behind Black Hole: Galactic Nuclei

August 15, 2021August 15, 2021 Pooja Kashyap

Black holes are the most fascinating phenomena in the universe. Any new finding regarding the intricacies of black hole makes us wonder how less we know about it. This uncanny object is famous for ingesting huge quantities of matter from its surroundings, beaming with glittering luminosity and spilling out small portion of this matter by means of very powerful jets.

Stars Spin Faster as They Age: Weakened Magnetic Braking

April 27, 2021April 27, 2021 Pooja Kashyap

Stars are the building blocks of galaxies. Turbulence, that is, the result of chaotic changes in pressure and velocity deep within the dust clouds gives rise to some mass. This “mass” results in stellar gravity due to which, the peripheral dust and gas start to disintegrate under its own gravitational attraction. And hence, star formation takes place.

Oumuamua was Scrapped from a Pluto-like Planet: Messenger from Afar

March 17, 2021March 17, 2021 Pooja Kashyap

Oumuamua was name given to the mysterious interstellar object that passed through our solar system in 2017. What’s special about this object was, it happened to be the first that had come from ‘outside’ our solar system.

December 18, 2020December 18, 2020 Pooja Kashyap

Storage and pumping fuel to rocket engines are the main challenges for travel beyond Earth and between celestial bodies. Researchers at Washington State University (WSU) have come up with an interesting idea of paper folding technique to bring about the desired architecture.

Tidal Disruption causes Dark Matter to Evaporate: Intra Galactic Interactions

December 7, 2020December 7, 2020 Pooja Kashyap

Dark matter is one of the key ingredients in the understanding of evolution and in the formation of galaxies. Majority of scientists are of the view that dark matter consists of weakly interacting massive particles (WIMP). It is because of their weak interactions with matter that we see around, it becomes extremely difficult to detect.

Borexino detects CNO Fusion Cycle in Sun: Stellar Energy Generation

November 28, 2020November 28, 2020 Pooja Kashyap

Until now, astronomers had classified nuclear fusion that is taking place within the core of the Sun is due to Proton Proton Cycle. However, an international scientific collaboration at the INFN Gran Sasso Laboratories, Italy were able to detect neutrinos in the Sun by the CNO cycle.

A Three Agent Robotic System For Red Planet: Mars Exploration

September 23, 2020September 23, 2020 Pooja Kashyap

One of the most famous quotes from Interstellar ‘Mankind was born on Earth. It was never meant to die here”, throws light on the intrinsic fear that we all have. Fear of being extinct. Mankind wants to leave the planet Earth, thus escaping extinction. And this is the motif behind all missions of Mars.

Our devices might never go out of internet coverage area. Musk plans to provide global internet connection to everyone and anywhere in the world. Connectivity speed too will be above average, that is, more than home WIFI (50Mb/s).

Io’s Atmosphere Is Daily Collapsing And Repairing: The Jupiter System

August 8, 2016 Pooja Kashyap

Documenting atmospheric changes in eclipse on Io, the innermost of the four Galilean moons of the planet Jupiter, has always been a challenging job. The darkness caused by planet’s shadow makes it impossible to observe atmosphere on its moon.

Center of Our Galaxy is Devoid of Stellar Populations: Cepheid Desert

August 2, 2016 Pooja Kashyap

Recent research lead by Prof Noriyuki Matsunaga and his team of astronomers at the University of Tokyo suggest that our understanding of Milky Way Galaxy is still not complete. The team discovered that major portion of the region surrounding the center of our Galaxy is devoid of young stars, a study that contradicts the conventional thinking. In an interview covered by Universe Today, Dr. Andrea Ghez, a professor of physics and astronomy at UCLA, said the probability of formation of young stars at the center of the galaxy is high.…
