Lyman Break Galaxy (LBG) candidates at z>10 are rapidly being identified in JWST/NIRCam observations. Due to the (redshifted) break produced by neutral hydrogen absorption of rest-frame UV photons, these sources are expected to drop out in the bluer

Y. Aaron, Zavala, Jorge A.

We present rest-frame optical emission-line flux ratio measurements for five $z>5$ galaxies observed by the JWST Near-Infared Spectrograph (NIRSpec) in the SMACS 0723 Early Release Observations. We add several quality-control and post-processing step

Theoretical ISM pressure and electron density diagnostics for local and high-redshift galaxies

Autor: Kewley, Lisa J., Nicholls, David C., Sutherland, Ralph S., Rigby, Jane R., Acharyya, Ayan, Dopita, Michael A., Bayliss, Matthew B.

Publikováno v: The Astrophysical Journal, Volume 880, Issue 1, article id. 16, 24 pp. (2019)

We derive new self-consistent theoretical UV, optical, and IR diagnostics for the ISM pressure and electron density in the ionized nebulae of star-forming galaxies. Our UV diagnostics utilize the inter-combination, forbidden and resonance lines of si

Calibrating Interstellar Abundances using SNR Radiative Shocks

Autor: Dopita, Michael A., Seitenzahl, Ivo R., Sutherland, Ralph S., Nicholls, David C., Vogt, Frédéric P. A., Ghavamian, Parviz, Ruiter, Ashley J.

Using integral field data we extract the optical spectra of shocked interstellar clouds in Kepler's supernova remnant located in the inner regions of our Galaxy, as well as in the Large Magellanic Cloud (LMC), the Small Magellanic Cloud (SMC), NGC682
