BDO and partner schools: Living and learning through the pandemic

Published June 14, 2021, 11:58 AM Manuel S. Enverga University It’s not only entrepreneurs who have been struggling through the pandemic schools have also been doing their best to survive and continue operations for the sake of students and teachers. One example of how a school has heroically met the challenge of the pandemic is Manuel S. Enverga University (MSEUF) in Lucena, Quezon Province. Founded in 1947, the university has provided many generations the hope of learning and a brighter future. When the pandemic struck, the university had to adjust its administrative operations in order to assure the safety of its teachers and students while continuing to provide quality education.

Physics - Black Holes Studied as a Population

Black Holes Studied as a Population May 7, 2021• Physics 14, 67 The latest dataset from gravitational-wave observatories has enough events to allow researchers to study properties of the whole population of black holes. F. Elavsky and A. Geller/Northwestern Univ./LIGO-Virgo Collaboration Black holes (blue), neutron stars (orange), and compact objects of uncertain nature (gray) detected via gravitational waves through September 2019. Each binary merger involves three compact objects: the two coalescing objects and the final remnant.

This Black Hole Was Hiding a Massive Surprise

This Black Hole Probably Shouldn’t Exist Marina Koren There’s a spot in space, thousands of light-years from here, that might best be described as a cosmic amusement park. A supergiant star, so hot that it glows electric blue, and a black hole spin around each other at extraordinary speeds, orbiting so closely that some of the star’s material is pulled toward the black hole. The stellar particles swirl around the invisible object in a tilt-a-whirl of luminous reds and oranges. What the black hole doesn’t swallow, it hurls into space, producing intense jets of radiation. There is a lot going on,” James Miller-Jones, an astrophysicist at Curtin University in Australia, told me.

Black Holes Keep Running Into One Another

A New Era of Black Holes Is Here Thomas Lewton © MARK GARLICK / SCIENCE PHOTO LIBRARY / GETTY When the first black-hole collision was detected in 2015, it was a watershed moment in the history of astronomy. Using gravitational waves, astronomers were observing the universe in an entirely new way. But this first event didn’t revolutionize our understanding of black holes nor could it. This collision would be the first of many, astronomers knew, and only with that bounty would answers come. “The first discovery was the thrill of our lives,” says Vicky Kalogera, an astrophysicist at Northwestern University and part of the Laser Interferometer Gravitational-Wave Observatory (LIGO) collaboration that made the 2015 detection. “But you cannot do astrophysics with one source.”
