MOCSS: Multi-Object Coronagraphy for JWST/NIRSpec Slitless Spectroscopy

We present an experimental JWST/NIRSpec observational method to obtain $R\gtrsim1000$ G140M/F100LP slitless spectroscopic observations. This"Multi-Object Coronagraphy for Slitless Spectroscopy"(MOCSS) technique involves opening essentially all microshutters on NIRSpec simultaneously while closing shutters corresponding...

A Single Line Emitter Identified in an Unbiased Search with JWST/NIRSpec: Multiobject Coronagraphy for Slitless Spectroscopy

We report the detection of a previously unknown object with a single emission line within the Hubble Ultra Deep Field, using a new JWST NIRSpec technique called Multiobject Coronagraphy for Slitless Spectroscopy (MOCSS) with the G140M/F100LP observing mode. The MOCSS technique involves opening almost all the shutters o...

Stellar Yields of Rapidly Rotating Population III Stars for the High Redshift Universe

JWST has revealed rapid nitrogen enrichment in high redshift galaxies, renewing the need for stellar yields that follow metal free stars beyond the main sequence and across their final fates. We present Geneva stellar evolution models of rapidly rotating Pop~III stars with $5 \leq M_{\rm ini}/M_\odot \leq 200$ and $\up...
