We present a homogeneous chemical abundance analysis of five of the most metal-poor stars in the Sculptor dwarf spheroidal galaxy. We analyze new and archival high resolution spectroscopy from ...

Scientists from Helsinki, Durham and Toulouse universities used data from NASA's Hubble and the European Space Agency's Gaia ...

We report on the abundance analysis of two red giants in the faint Hercules dwarf spheroidal (dSph) galaxy. These stars show a remarkable deficiency in the neutron-capture elements, while the ...

Abstract: We apply prolate spheroidal wave functions of order zero as basis functions in the pseudospectral method for frequency-domain electromagnetic simulation problems. Like the traditional ...

Compared with the existing cascaded configuration, the structure of spheroidal-cavity-overlapped FBG is smaller. In addition, due to the high-quality smooth surface, the concave shape also helps ...

Scientists from Helsinki, Durham and Toulouse universities used data from NASA's Hubble and the European Space Agency's Gaia ...

Explore wormholes: theoretical cosmic shortcuts through spacetime. Learn if they're real, what they might look like, and ...

ASKAP detects a perfectly spherical supernova remnant called ‘Telios’ Telios’ true distance and size remain unclear due to ...

New research has cast doubt on the long-held theory that our galaxy, the Milky Way, will collide with its largest neighbour, the Andromeda galaxy, in 4.5 billion years-time.

Here, the authors present a combinatorial titration methodology to probe in situ a binary assembly mechanism between spheroidal micelles and β-sheet polymers of peptide amphiphiles, which ...
