X-ray binary GX 3+1 investigated with AstroSat

Using the AstroSat spacecraft, Indian astronomers have investigated a low-mass X-ray binary known as GX 3+1. The study provided more insights into the properties of GX 3+1 and detected a thermonuclear burst from this source. ...

A new duality solves a physics mystery

In conventional wisdom, producing a curved space requires distortions, such as bending or stretching a flat space. A team of researchers at Purdue University have discovered a new method to create curved spaces that also ...

Supernova reveals its secrets to team of astronomers

An international group of astronomers led by Benjamin Thomas of The University of Texas at Austin has used observations from the Hobby-Eberly Telescope (HET) at the university's McDonald Observatory to unlock a puzzling mystery ...

Enhancing simulations of curved space with qubits

One of the mind-bending ideas that physicists and mathematicians have come up with is that space itself—not just objects in space—can be curved. When space curves (as happens dramatically near a black hole), sizes and ...

New dates for the start of Viking-age trade

Mobility shaped the human world profoundly long before the modern age. But archaeologists often struggle to create a timeline for the speed and impact of this mobility. An interdisciplinary team of researchers at the Danish ...

Indian astronomers investigate X-ray binary GRS 1915+105

Using the AstroSat spacecraft, astronomers from India have observed an X-ray binary system known as GRS 1915+105. The satellite allowed the researchers to conduct a comprehensive study of this object, yielding essential information ...

New mathematical solutions to an old problem in astronomy

For millennia, humanity has observed the changing phases of the Moon. The rise and fall of sunlight reflected off the Moon, as it presents its different faces to us, is known as a "phase curve". Measuring phase curves of ...
