UrduCosmologists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory are experimenting with a prototype radio telescope, called the Baryon Mapping Experiment (BMX). Built at the Lab in 2017, the prototype serves as a testbed for managing radio interference and developing calibration techniques. Lessons learned from the prototype could pave the way for Brookhaven to develop a much larger radio telescope in collaboration with other national Labs, universities, and international partners.

New Distance Measurements Bolster Challenge to Basic Model of Universe
A cosmic measurement technique independent of all others adds strong evidence pointing to a problem with the current theoretical model describing the composition and evolution of the Universe.
Theoretical breakthrough shows quantum fluids rotate by corkscrew mechanism
Scientists performed simulations of merging rotating superfluids, revealing a peculiar corkscrew-shaped mechanism that drives the fluids into rotation without the need for viscosity.
Meet the Intern Using Quantum Computing to Study the Early Universe
During an internship at Brookhaven National Laboratory, Juliette Stecenko is using modern supercomputers and quantum computing platforms to perform astronomy simulations that may help us better understand where we came from.
Largest collection of 3D supernova simulations leads to new insights on explosion dynamics
Researchers using DOE supercomputers, including Argonne’s Theta, produced pivotal 3D simulations to elucidate the physics behind the collapse of massive stars.
Argonne and CERN weigh in on the origin of heavy elements
Nuclear physicists from Argonne National Laboratory led an international physics experiment conducted at CERN that utilizes novel techniques developed at Argonne to study the nature and origin of heavy elements in the universe.
Looking Up From the Mountaintop: Q&A with a Telescope Instrument’s Lead Observer
In this Q&A Satya Gontcho A Gontcho, a lead observer for the Dark Energy Spectroscopic Instrument (DESI), shares her experiences at the DESI site near Tucson, Arizona, including evening observing stints to run through detailed checklists and probe how the instrument’s components are working.
Berkeley Lab Cosmologists Are Top Contenders in Machine Learning Challenge
In a machine learning challenge dubbed the 2020 Large Hadron Collider Olympics, a team of cosmologists from Berkeley Lab developed a code that best identified a mock signal hidden in simulated particle-collision data.
Meteorites lend clues to origins of earliest history of solar system
Lawrence Livermore National Laboratory (LLNL) scientists and a collaborator from the University of Münster reviewed recent work that shows how meteorites exhibit a fundamental isotopic dichotomy between non-carbonaceous (NC) and carbonaceous (CC – rocks or sediments containing carbon or its compounds) groups, which most likely represent material from the inner and outer solar system.
Six Berkeley Lab Scientists Named AAAS Fellows
Six scientists from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have been named Fellows of the American Association for the Advancement of Science (AAAS).
Russian astronomer comments on Nobel Prize in physics
MOSCOW (MIPT) — The discovery by Michel Mayor and Didier Queloz was momentous in that they made it very clear how exoplanets may be sought using what is known as the radial velocity method, says Alexander Rodin from the Moscow Institute…
AIP Congratulates 2019 Nobel Prize Winners in Physics
WASHINGTON, D.C., October 8, 2019 — The 2019 Nobel Prize in physics was awarded today to James Peebles, Michel Mayor, and Didier Queloz “for contributions to the evolution of the universe and Earth’s place in the cosmos.” “AIP is delighted…
AI technique does double duty spanning cosmic and subatomic scales
While high-energy physics and cosmology seem worlds apart in terms of sheer scale, physicists and cosmologists at Argonne are using similar machine learning methods to address classification problems for both subatomic particles and galaxies.
Department of Energy Announces $21.4 Million for Quantum Information Science Research
The following news release was issued on Aug. 26, 2019 by the U.S. Department of Energy (DOE). It announces funding that DOE has awarded for research in quantum information science related to particle physics and fusion energy sciences. Scientists at DOE’s Brookhaven National Laboratory are principal investigators on two of the 21 funded projects.
Deep Learning Reveals Mysteries of Deep Space
The Science How do you determine the measurable “things” that describe the nature of our universe? To answer that question, researchers used CosmoFlow, a deep learning technique, running on a National Energy Research Scientific Computing Center supercomputer. They analyzed large,…
