SPURS: An Ultra-deep View Inside the Compact, Nitrogen-Enriched Nuclei of Little Red Dots
Mengtao Tang, Daniel P. Stark, Charlotte A. Mason +7
We present the first ultra-deep rest-UV spectroscopy of four UV-bright Little Red Dots (LRDs), obtained from the SPURS Cycle 4 Large Program. The spectra reveal broad CIV (FWHM $\a…
OutThere Survey: Addressing and with a population of average galaxies at z2
Ravi Jaiswar, Anshu Gupta, Elisabete da Cunha +24
Constraining the major contributors to the ionisation of the early universe is an ongoing endeavour of high-redshift galaxy research. We measure the ionising photon production effi…
SPURS: Massive Stars, Dense Gas, and Ly Escape in GN-z11 at
Zuyi Chen, Daniel P. Stark, Charlotte A. Mason +6
We present ultra-deep {\it JWST} spectroscopy of GN-z11 () obtained through the SPURS Cycle 4 Large Program, providing the deepest rest-UV view yet obtained of a galaxy at…
A first systematic study of [OIII] 88m at : two luminous oxygen lines and a powerful ionized outflow in the first 600 million years
Hiddo S. B. Algera, John R. Weaver, Tom J. L. C. Bakx +35
We present deep ALMA Band 7 observations of the [OIII] m line and underlying dust continuum emission in four UV-bright, gravitationally lensed (magnification ), JW…
A Fleeting GLIMPSE of N/O Enrichment at Cosmic Dawn: Evidence for Wolf Rayet N Stars in a z = 6.1 Galaxy
Danielle A. Berg, Rohan P. Naidu, John Chisholm +18
We present the discovery of extreme nitrogen enrichment by Wolf Rayet nitrogen stars (WN) in the metal-poor (~10% Z_odot), lensed, compact (R_eff ~ 20 pc) galaxy RXCJ2248 at z=6.1,…
Deep JWST spectroscopy of galaxies in a candidate ionized bubble at : probing reionization at pMpc scales with Ly emission
Lily Whitler, Daniel P. Stark, Charlotte A. Mason +5
Strong Ly emission observed from galaxies when the Universe is expected to be highly neutral is thought to trace large ionized regions that facilitate the transmission of Ly…
The Growth of Dust in Galaxies in the First Billion Years with Applications to Blue Monsters
Desika Narayanan, Paul Torrey, Daniel Stark +9
A combination of JWST observations at z~12-14 and ALMA observations of extremely dust-rich systems at z~6 has demonstrated that dust grows extremely fast in the early Universe, wit…
