A Dyson sphere around a black hole

TL;DR: In this article, a Dyson sphere around a stellar-mass black hole in the Milky Way (10kpc away from us) is detected in the ultraviolet (10−400nm), optical (400−760nm) and near-infrared (µ−5μm) wavelengths via the waste heat radiation using current telescopes such as Galaxy Evolution Explorer Ultraviolet Sky Surveys.
Journal ArticleDOI

ALMA Detections of [O iii] and [C ii] Emission Lines From A1689-zD1 at z = 7.13

TL;DR: In this paper , the authors measured the redshift of A1689-zD1 as 7.133 ± 0.005 based on the [C ii] and [O iii] emission lines, consistent with that adopted by Bakx et al.
Journal ArticleDOI

Galaxy source counts at 7.7 $\mu$m, 10 $\mu$m and 15 $\mu$m with the James Webb Space Telescope

TL;DR: In this article , the authors presented mid-infrared galaxy number counts based on the Early Release Observations obtained by the James Webb Space Telescope (JWST ) at 7.7, 10- and 15- ǫ m (F770W, F1000W and F1500W, respectively) bands of the mid-Infrared Instrument (MIRI).
Journal ArticleDOI

Constraining the hubble constant and its lower limit from the proper motion of extragalactic radio jets

TL;DR: In this paper , a model-free and distance-free method to constrain the Hubble constant was proposed by combining Friedman-Lemaître-Robertson-Walker cosmology with geometrical relation of the proper motion of extragalactic jets.
