The formation time scales of quiescent galaxies can be estimated in two different ways: by their star formation history and by their chemistry. Previously, the...
ZW 0855+06: A Wolf-Rayet Dwarf Galaxy Triggered by a Dwarf-Dwarf Interaction
We present narrowband (Hα and adjacent continuum) and broadband (B and V) optical images of the dwarf Wolf-Rayet galaxy Zw 0855+06 and its companion, together...
[Mg/Fe] and variable initial mass function: Revision of [α/Fe] for massive galaxies
Observations of nearby massive galaxies have revealed that they are older and richer in metals and magnesium than their low-mass counterparts. In particular...
μ<SUB>⋆</SUB> masses: weak-lensing calibration of the Dark Energy Survey Year 1 redMaPPer clusters using stellar masses
We present the weak-lensing mass calibration of the stellar-mass-based μ ⋆ mass proxy for redMaPPer galaxy clusters in the Dark Energy Survey Year 1. For the...
