The Astrophysical Journal Letters, 2023 GN-z11 is an unusually luminous high-redshift galaxy that was recently observed to have strong nitrogen lines while at the same time lacking traditional signatures of active galactic nucleus activity.

Rapid Chemical Enrichment by Intermittent Star Formation in GN-z11
The Astrophysical Journal LettersWe interpret the peculiar supersolar nitrogen abundance recently reported by the James Webb Space Telescope observations for GN-z11 ( z = 10.6) using our state-of-the-art chemical evolution models.

GN-z11 in Context: Possible Signatures of Globular Cluster Precursors at Redshift 10
The Astrophysical JournalThe first JWST spectroscopy of the luminous galaxy GN-z11 simultaneously established its redshift at z = 10.6 and revealed a rest-ultraviolet spectrum dominated by signatures of highly ionized nitrogen, which has so far defied clear interpretation.

The GN-z11-Flash Event can be a Satellite Glint [PDF]
Research Notes of the AAS, 2021 Abstract Recently Jiang et al. reported the discovery of a possible short duration transient, detected in a single image, spatially associated with a z ∼ 11 galaxy. Jiang et al. and Kann et al. suggested the transient originates from a γ-Ray Burst (GRB), while Padmanabhan & Loeb argued the flash is consistent with a supernova shock ...

Evidence for GN-z11 as a luminous galaxy at redshift 10.957 [PDF]
Nature Astronomy, 2020 GN-z11 was photometrically selected as a luminous star-forming galaxy candidate at redshift z > 10 based on Hubble Space Telescope (HST) imaging data. Follow-up HST near-infrared grism observations detected a continuum break that was explained as the Ly-alpha break corresponding to z = 11.09 (+0.08-0.12).

GN-z11-flash in the Context of Gamma-Ray Burst Afterglows [PDF]
Research Notes of the AAS, 2020 Abstract The recently discovered rapid transient GN-z11-flash has been suggested to be the prompt-emission ultraviolet (UV) flash associated with a gamma-ray burst (GRB) serendipitously exploding in the ultra-high-z galaxy GN-z11. We here place the flash into the context of the early UV emission of GRBs, and find it is in agreement with ...

Signatures of population III supernovae at Cosmic Dawn: the case of GN-z11-flash [PDF]
General Relativity and Gravitation, 2022 AbstractWe illustrate the observability of the end stages of the earliest (Population III) stars at high redshifts$$z \gtrsim 10$$z≳10, using the recently observed transient, GN-z11-flash as an example. We find that the observed spectrum of this transient is consistent with its originating from a shock-breakout in a Population III supernova occurring ...

The Breast, 2013 The ACOSOG Z0011 (Z11) trial demonstrated the presence of a group of breast cancer patients with some residual axillary disease who did not benefit from axillary lymph node dissection (ALND) in the presence of whole breast radiotherapy and systemic therapy at short term follow-up.

Are the Conclusions of Z11 Relevant to Community Practice? [PDF]
Clinical Breast Cancer, 2015 Findings of the American College of Surgeons Oncology Group (ACOSOG) Z11 trial have proven controversial, leaving physicians divided over which patients with positive sentinel lymph nodes (+SLNs) benefit from axillary lymph node dissection (ALND). We reviewed our experience at our institution with Z11-eligible patients who did not undergo ALND and ...
