We examine the gravitational lens hypothesis for the nearly perfect ring around the elliptical galaxy 373 in cluster A2218. We first investigate analytically the variation of the mean radius …
The galaxy cluster Abell 2218, at , is well-known for the discrepancy between mass estimates derived from X-ray and strong lensing analyses. With the present XMM-Newton observation…
We present the identification of a bright submillimeter (submm) source, SMM J163555.5+661300, detected in the lensing cluster Abell 2218, for which we have accurately determined …
We have made mass maps of three strong-lensing clusters, Abell 3827, Abell 2218 and Abell 1689, in order to test for mass–light offsets. The technique used is GRALE, which enables …
Scanning electrochemical microscopy (SECM) is a powerful and versatile technique for visualizing the local electrochemical activity of a surface as an ultramicroelectrode tip is moved …
We survey recent results in the mathematical literature on the equations of incompressible fluid dynamics, highlighting common themes and how they might contribute to the …
We present results from a deep photometric study of the rich galaxy cluster Abell 2218 (z= 0.18) based on archival Hubble Space Telescope WFPC2 F606W images. These have been …
A mass model of the rich cluster A2218 is presented based on optical and new near-infrared images of arc(let)s and the ROSAT/HRI X-ray map. A lensing model is proposed with two …
This paper presents the "Ukraine Support Tracker", which lists and quantifies military, financial and humanitarian aid to Ukraine in the context of Russia's war against Ukraine. We track …
… VIR-2218 and AS(N-1)3’VIR-2218 were detectable in urine through the last measured time … -2218 over 0–24 h postdose. Based on pharmacokinetics in preclinical species, VIR-2218 …
