The most distant quasar yet discovered sets constraints on the formation mechanism of black holes. Its light spectrum has tantalizing features that are...
Monthly Notices of the Royal Astronomical Society, Royal Astronomical Society, 29 novembre 2022, Volume : 518, Numéro : 4
We present 65 extremely dust-obscured galaxies from the UltraVISTA DR3 survey of the COSMOS field at 1 < z < 4. In contrast to other studies of dusty galaxies,...
Monthly Notices of the Royal Astronomical Society, Oxford Academic, 21 décembre 2023, Volume : 527, Numéro : 4
We use CANUCS JWST/NIRCam imaging of galaxies behind the gravitationally-lensing cluster MACS J0417.5-1154 to investigate star formation burstiness in low-mass...
The Astrophysical Journal, IOP Publishing, 29 janvier 2020, Volume : 889, Numéro : 2
We present a search for companion [C ii] emitters to known luminous sources at 6 < z < 6.5 in deep, archival ALMA observations. The observations are deep...
The Astrophysical Journal Letters, 31 octobre 2011, Volume : 742, Numéro : 1
It has been claimed that there is a large population of obscured, accreting black holes at high redshift and that the integrated black hole density at z = 6 as...
Aims. Integral field spectroscopy (IFS) with JWST NIRSpec will significantly improve our understanding of the first quasars, by providing spatially resolved,...
The Astrophysical Journal Letters, IOP, 22 mai 2023, Volume : 949, Numéro : 1
We present the first results on the spatial distribution of dust attenuation at 1.0 < z < 2.4 traced by the Balmer decrement, Hα/Hβ, in emission-line galaxies...
We present rest-frame optical data of the compact z = 5.55 galaxy GS_3073 obtained using the integral field spectroscopy mode of the Near-InfraRed Spectrograph...
The Astrophysical Journal Letters, IOP, 11 octobre 2021, Volume : 920, Numéro : 1
Identifying stars formed in pristine environments (Population III) within the first billion years is vital to uncovering the earliest growth and chemical...
Monthly Notices of the Royal Astronomical Society: Letters, Royal Astronomical Society, 9 mai 2023, Volume : 523, Numéro : 1
Using CANUCS imaging we found an apparent major merger of two z ∼ 5 ultra-low-mass galaxies (M⋆∼10⁷M⊙ each) that are doubly imaged and magnified ∼12–15× by the...
