Stellar content of the metal-poor galaxy DDO 68

Astronomy Letters, 2014
Based on archival Hubble Space Telescope ACS/WFC images, we have performed stellar photometry for the metal-poor galaxy DDO 68. The apparent distributions of stars of different ages and stellarmetallicity determinations indicate that DDO68 is a systemof two galaxies that have different stellar metallicities (Z = 0.004 and 0.001) and are in the stage of

The Atacama Cosmology Telescope: the stellar content of galaxy clusters selected using the Sunyaev–Zel'dovich effect

open access: yesMonthly Notices of the Royal Astronomical Society, 2013
We present a first measurement of the stellar mass component of galaxy clusters selected via the Sunyaev-Zel’dovich (SZ) effect, using 3.6 and 4.5 mu m photometry from the Spitzer Space Telescope.

Stellar content of NGC 404 – The nearest S0 Galaxy

open access: yesAstronomy and Astrophysics, 2003
We report $V -$band and $I -$band CCD stellar and surface photometry of the galaxy NGC 404 , taken with HST WFPC2 and the 2.5 m Nordic telescope. The colour-magnitude diagram for the stars in this galaxy is typical of that of spheroidal systems (i.e.

LoCuSS: scaling relations between galaxy cluster mass, gas, and stellar content [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2019
International audienceWe present a simultaneous analysis of galaxy cluster scaling relations between weak-lensing mass and multiple cluster observables, across a wide range of wavelengths, that probe both gas and stellar content.
