Can Wolf-Rayet stars be the missing ingredient to explain high-z He II ionizing radiation?
G. González-Torà, A. A. C. Sander, E. Egorova +7
Classical Wolf-Rayet (WR) stars are hot, massive stars with depleted hydrogen. At low metallicities (Z), WN3-type WR stars have relatively thin winds and are major sources of ioniz…
SDSS-V LVM: Detectability of Wolf-Rayet stars and their He II ionizing flux in low-metallicity environments I. The weak-lined, early-type WN3 stars in the SMC
G. González-Torà, A. A. C. Sander, E. Egorova +18
The Small Magellanic Cloud (SMC) is the nearest low-metallicity dwarf galaxy. Its proximity and low reddening has enabled us to detect its Wolf-Rayet (WR) star population with 12 k…
Temperature based radial metallicity gradients in nearby galaxies
K. Kreckel, R. J. Rickards Vaught, O. V. Egorov +14
Gas-phase abundances provide insights into the baryon cycle, with radial gradients and 2D metallicity distributions tracking how metals build up and redistribute within galaxy disk…
