We present spatially resolved spectroscopic observations of the planetary nebula NGC 6720, the Ring Nebula, taken during the science verification phase of WEAVE, a new instrument m…
Fossil group origins XIV: The radial orbits of A267
S. Zarattini, A. Biviano, I. Bartalucci +3
Fossil groups (FGs) are groups or clusters of galaxies with a single, massive, central galaxy and with a clear lack of L* galaxies. The physical reason for their large magnitude ga…
The Tremaine-Weinberg method at high redshifts
Mahmood Roshan, Asiyeh Habibi, J. Alfonso L. Aguerri +11
This paper examines the reliability of the Tremaine-Weinberg (TW) method in measuring the pattern speed of barred galaxies at high redshifts. Measuring pattern speeds at high redsh…
