A faint M Lyman-continuum leaker candidate in the epoch of reionization: Unprecedented Ly properties at z=5.725
M. Messa, E. Vanzella, T. Morishita +10
We report the unprecedented Ly properties of AMORE6, an extremely metal-poor (), low-mass (), and ultracompact (effec…
JWST Lensed Quasar Dark Matter Survey III: Dark Matter Sensitive Flux Ratios and Warm Dark Matter Constraint from the Full Sample
R. E. Keeley, A. M. Nierenberg, D. Gilman +24
We present the full sample of measurements of the warm dust emission of 31 strongly-lensed, multiply imaged quasars, observed with JWST MIRI multiband imaging, which we use to cons…
JWST lensed quasar dark matter survey IV: Stringent warm dark matter constraints from the joint reconstruction of extended lensed arcs and quasar flux ratios
D. Gilman, A. M. Nierenberg, T. Treu +23
We present a measurement of the free-streaming length of dark matter (DM) and subhalo abundance around 28 quadruple image strong lenses using observations from JWST MIRI presented…
A Nitrogen-rich AGN Powering a Large Ionizing Bubble at z=8.63
Takahiro Morishita, Massimo Stiavelli, Charlotte A. Mason +5
We report the detection of Ly in CANUCS-LRD-z8.6, a recently discovered AGN at z = 8.63 by Tripodi et al. (2024), in new NIRSpec/MSA G140H/F070LP observations. We detect broad L…
Pristine Massive Star Formation Caught at the Break of Cosmic Dawn
Takahiro Morishita, Zhaoran Liu, Massimo Stiavelli +3
The existence of galaxies with no heavy elements is a key prediction of cosmological models. So far no "zero-metallicity", or Population~III, galaxies have been identified. Here, w…
The BoRG- Survey: Analogs at to the UV-luminous Galaxy Population at
Sofía Rojas-Ruiz, Guido Roberts-Borsani, Takahiro Morishita +7
The population of bright galaxies at discovered by JWST, including the so-called "blue monsters", has been difficult to reconcile with standard galaxy evolution models…
TDCOSMO XXIV. First spatially resolved kinematics of the lens galaxy obtained using JWST-NIRSpec to improve time-delay cosmography
Anowar J. Shajib, Tommaso Treu, Sherry H. Suyu +15
Spatially resolved stellar kinematics has become a key ingredient in time-delay cosmography to break the mass-sheet degeneracy in the mass profile and in turn provide a precise con…
TDCOSMO 2025: Cosmological constraints from strong lensing time delays
TDCOSMO Collaboration, Simon Birrer, Elizabeth J. Buckley-Geer +30
We present cosmological constraints from 8 strongly lensed quasars (hereafter, the TDCOSMO-2025 sample). Building on previous work, our analysis incorporated new deflector stellar…
TDCOSMO: XX. WFI2033--4723, the First Quadruply-Imaged Quasar Modeled with JWST Imaging
D. M. Williams, T. Treu, S. Birrer +5
Gravitational time delays offer unique, independent measurements of the Hubble constant, . Precise measurements of stand as one of the most pressing challenges in modern…
Potential Nitrogen Enrichment via Direct-Collapse Wolf-Rayet Stars in a Star-Forming Galaxy
Yechi Zhang, Takahiro Morishita, Massimo Stiavelli
We present analyses of a nitrogen-enriched star-forming galaxy, ID60001, at based on JWST/NIRSpec MSA spectroscopy and NIRCam photometry. From rest-frame optical emissio…
Metallicity Scatter Originating from Sub-kiloparsec Starbursting Clumps in the Core of a Protocluster at z=7.88
Takahiro Morishita, Massimo Stiavelli, Eros Vanzella +9
We present new JWST NIRSpec integral field unit (IFU) G395H/F290LP observations of a merging galaxy system at , part of A2744-z7p9, the most distant protocluster to date. T…
A recoiling supermassive black hole in a powerful quasar
Marco Chiaberge, Takahiro Morishita, Matteo Boschini +14
Supermassive black holes (SMBH) are thought to grow through accretion of matter and mergers. Models of SMBH mergers have long suffered the final parsec problem, where SMBH binaries…
