Abstract: Abstract In this study, a series of Bi2Te2-xS1+x compounds were prepared by traditional melting-quenching-annealing process. In the range of 0.03 ≤ x ≤ 0.25, Bi2Te2-xS1+x compounds possess the Bi2Te3 structure. S atoms preferentially fully occupy the Te(2) sites, while… read more here.

Abstract: We test if the cosmological zoom-in simulations of isolated galaxies from the FIRE project reproduce the properties of ultra diffuse galaxies (UDGs). We show that outflows that dynamically heat galactic stars, together with a passively… read more here.
