GN-z11: Witnessing the formation of second-generation stars and an accreting massive black hole in a massive star cluster [PDF]
Astronomy & Astrophysics, 2023 We explore the possibility of the N-rich young proto-galaxy GN-z11, recently observed at z=10.6 by JWST, being the result of the formation of second generation stars from pristine gas and asymptotic giant branch (AGB) ejecta in a massive globular cluster

Art as an Asset: Evidence from Keynes the Collector
Review of Asset Pricing Studies, 2019 The risk-return characteristics of art as an asset have been previously studied through aggregate price indexes. By contrast, we examine the long-run buy-and-hold performance of an actual portfolio, namely, the collection of John Maynard Keynes.

Insight into the starburst nature of Galaxy GN-z11 with JWST MIRI spectroscopy [PDF]
Astronomy & AstrophysicsThis paper presents a deep MIRI/JWST medium-resolution spectroscopy (MRS) covering the rest-frame optical spectrum of the GN-z11 galaxy. The O,III 5008Å and Hα emission lines are detected and spectroscopically resolved. The line profiles are well modeled
