Astrophysicists from Johns Hopkins University have proposed a clever new way of shedding light on the mysterious dark matter believed to make up most of the universe. The irony is they want to try to pin down the nature of this unexplained phenomenon by using another, an obscure cosmic emanation known as “fast radio bursts.”

When an astronomical observatory in the United States this winter detected a whisper of two black holes colliding in deep space, scientists celebrated a successful effort to confirm Albert Einstein’s prediction of gravitational waves. A team of Johns Hopkins University astrophysicists wondered about something else: Had the experiment found the “dark matter” that makes up most of the mass of the universe?
The universe appears to be expanding faster now than predicted by measurements of the rate as seen shortly after the Big Bang, a study led by a Johns Hopkins University scientist has found.
High in the Andes Mountains of northern Chile a unique Johns Hopkins University observatory has just achieved “first light,” the first time the telescope has collected radiation from space.
Research led by Johns Hopkins University scientists has found new persuasive evidence that could help solve a long-standing mystery in astrophysics: why did the pace of star formation in the universe slow down some 11 billion years ago?
An international team of astrophysicists led by a Johns Hopkins University scientist has for the first time witnessed a black hole swallowing a star and ejecting a flare of matter moving at nearly the speed of light.
Johns Hopkins University’s Marc Kamionkowski is a winner of the 2015 Dannie Heineman Prize for Astrophysics, one of the top prizes in the field, the American Astronomical Society (AAS) and the American Institute of Physics (AIP) announced today. The honor, which is awarded annually to outstanding mid-career scientists, carries a cash prize of $10,000 that will be split between Kamionkowski and his co-recipient, David Spergel of Princeton University.
Massive black holes spewing out radio-frequency-emitting particles at near-light speed can block formation of new stars in aging galaxies, a study has found.
Johns Hopkins astrophysicist Brice Ménard has been awarded a 2014 David and Lucile Packard Foundation Fellowship for Science and Engineering. Ménard plans to use this fellowship to work on a new technique to estimate the distance of galaxies and then explore new directions of research.
When a solar flare filled with charged particles erupts from the sun, its magnetic fields sometime break a widely accepted rule of physics. The flux-freezing theorem dictates that the magnetic lines of force should flow away in lock-step with the particles, whole and unbroken. Instead, the lines sometimes break apart and quickly reconnect in a way that has mystified astrophysicists. But in a paper published in the May 23 issue of the journal Nature, an interdisciplinary research team led by a Johns Hopkins mathematical physicist says it has found a key to the mystery.
A team of Johns Hopkins astrophysicists using NASA’s Hubble Space Telescope has detected a distant Type Ia supernova, the farthest stellar explosion that can be used to measure the expansion rate of the universe. The supernova is the remnant of a star that exploded 9 billion years ago.
Marc Kamionkowski, considered one of the world’s leading theoretical physicists for his work in large-scale structures and the early history of the universe, will join the faculty in the Henry A. Rowland Department of Physics and Astronomy at The Johns Hopkins University’s Krieger School of Arts and Sciences on July 1. An endowed professor at California Institute of Technology, Kamionkowski has spent much of his career researching astrophysics, cosmology and elementary particle theory.
Johns Hopkins University astrophysicist Charles Bennett and two colleagues today have been awarded this year’s $1 million Shaw Prize in astronomy for groundbreaking research determining the precise age, composition and curvature of the universe.
A team led by Johns Hopkins astrophysicist Charles L. Bennett has won a $5 million National Science Foundation grant – administered through the stimulus act – to build an instrument designed to probe what happened during the universe’s first trillionth of a second, when it suddenly grew from submicroscopic to astronomical size in far less than time than it takes to blink your eye.
