We present the deepest constraints yet on the median rest-UV+optical spectral energy distribution (SED) of z ∼ 10 galaxies prior to James Webb Space Telescope science operations. We constructed stacks based on four robust J _125 dropouts, previousl

We report 18 dust continuum detections ($\geq 3.3\sigma$) at $\sim88{\rm \mu m}$ and $158{\rm \mu m}$ out of 49 ultraviolet(UV)-bright galaxies ($M_{\rm UV} < -21.3$ mag) at $z>6.5$, observed by the Cycle-7 ALMA Large Program, REBELS and its pilot pr

We present specific star-formation rates for 40 UV-bright galaxies at $z\sim7-8$ observed as part of the Reionization Era Bright Emission Line Survey (REBELS) ALMA large program. The sSFRs are derived using improved measures of SFR and stellar masses

Blue Rest-Frame UV-Optical Colors in z~8 Galaxies from GREATS: Very Young Stellar Populations at ~650 Myr of Cosmic Time

Autor: Mauro Stefanon, Rychard J. Bouwens, Ivo Labbé, Garth D. Illingworth, Pascal A. Oesch, Pieter van Dokkum, Valentino Gonzalez

Publikováno v: The Astrophysical Journal, 927(1):48

Deep rest-optical observations are required to accurately constrain the stellar populations of $z\sim8$ galaxies. Due to significant limitations in the availability of such data for statistically complete samples, observational results have been limi

Galaxy stellar mass functions from z 10 to z 6 using the deepest Spitzer/Infrared Array camera data: no significant evolution in the Stellar-to-halo mass ratio of galaxies in the first gigayear of Cosmic Time

Autor: Pascal Oesch, Valentino Gonzalez, Rychard Bouwens, Ivo Labbé, Garth D. Illingworth, Mauro Stefanon

Publikováno v: The Astrophysical Journal, 922(1)

We present new stellar mass functions at z ∼ 6, z ∼ 7, z ∼ 8, z ∼ 9 and, for the first time, z ∼ 10, constructed from ∼800 Lyman-break galaxies previously identified over the eXtreme Deep Field and Hubble Ultra-Deep Field parallel fields
