“…Galaxy sizes defined by the effective radius, r e , have extensively been measured with Advanced Camera for Survey (ACS) and Wide Field Camera 3/IR-channel onboard HST for massive galaxies at 0 z 3 (e.g., van der Wel et al 2014) and z 3 − 4 Lyman break galaxies (LBGs) selected in the dropout technique (Steidel et al 1999) (e.g., Trujillo et al 2006;Toft et al 2007Toft et al , 2009Dahlen et al 2007;Grazian et al 2012;Huang et al 2013;McLure et al 2013). However, these studies, particularly at high-z, do not reach agreement on the size growth rate.…”

“…However, the controversial results of the slope and scatter evolution are obtained at z 3 − 4 (e.g., Huang et al 2013;Curtis-Lake et al 2014), probably due to large statistical uncertainties given by the small galaxy samples. An analysis with a large LBG sample would reveal the galaxy structure evolution up to z ∼ 10 with no significant statistical uncertainties, and allow us to understand disk formation mechanisms, internal star formation, and morphological evolution over cosmic time.…”

We present redshift evolution of galaxy effective radius r e obtained from the Hubble Space Telescope (HST) samples of ∼ 190, 000 galaxies at z = 0 − 10. Our HST samples consist of 176, 152 photo-z galaxies at z = 0 − 6 from the 3D-HST+CANDELS catalogue and 10, 454 Lyman break galaxies (LBGs) at z = 4 − 10 identified in CANDELS, HUDF09/12, and HFF parallel fields, providing the largest data set to date for galaxy size evolution studies. We derive r e with the same technique over the wide-redshift range of z = 0 − 10, evaluating the optical-to-UV morphological K-correction and the selection bias of photo-z galaxies+LBGs as well as the cosmological surface brightness dimming effect. We find that r e values at a given luminosity significantly decrease towards high-z, regardless of statistics choices (e.g. r e ∝ (1 + z) −1.10±0.06 for median). For star-forming galaxies, there is no evolution of the power-law slope of the size-luminosity relation and the median Sérsic index (n ∼ 1.5). Moreover, the r e -distribution is well represented by log-normal functions whose standard deviation σ ln re does not show significant evolution within the range of σ ln re ∼ 0.45 − 0.75. We calculate the stellar-to-halo size ratio from our r e measurements and the dark-matter halo masses estimated from the abundance matching study, and obtain a nearly constant value of r e /r vir = 1.0 − 3.5% at z = 0 − 8. The combination of the r e -distribution shape+standard deviation, the constant r e /r vir , and n ∼ 1.5 suggests a picture that typical high-z star-forming galaxies have disk-like stellar components in a sense of dynamics and morphology over cosmic time of z ∼ 0 − 6. If high-z star-forming galaxies are truly dominated by disks, the r e /r vir value and the disk formation model indicate that the specific angular momentum of the disk normalized by the host halo is j d /m d ≃ 0.5 − 1. These are statistical results for galaxies' major stellar components, and the detailed study of clumpy sub-components is presented in the paper II.

“…Smaller galaxy sizes at lower luminosities are sometimes used to argue that lensing shear has no effect on galaxy completeness (e.g., Maizy et al 2010). However, both the mass-size and the luminosity-size relations at high redshift are found to be very shallow following r M found by Huang et al (2013). These measurements are completely consistent with the surprisingly constant size scaling for late type galaxies at all redshifts z 0 3 = -seen in the CANDELS data set (r M e 0.22 µ ; see van der Wel et al 2014) and there is no convincing evidence for a change in these scaling relations at higher redshifts (but see Grazian et al 2012).…”

We search the complete Hubble Frontier Field data set of Abell 2744 and its parallel field for z 10 sources to further refine the evolution of the cosmic star formation rate density (SFRD) between z 8 and z 10 . We independently confirm two images of the recently discovered triply imaged z 9.8 source by Zitrin et al. and set an upper limit for similar z 10 galaxies with red colors of J H 1.2 125 160 -> in the parallel field of Abell 2744. We utilize extensive simulations to derive the effective selection volume of Lyman-break galaxies at z 10 , both in the lensed cluster field and in the adjacent parallel field. Particular care is taken to include position-dependent lensing shear to accurately account for the expected sizes and morphologies of highly magnified sources. We show that both source blending and shear reduce the completeness at a given observed magnitude in the cluster, particularly near the critical curves. These effects have a significant, but largely overlooked, impact on the detectability of high-redshift sources behind clusters, and substantially reduce the expected number of highly magnified sources. The detections and limits from both pointings result in an SFRD which is consistent within the uncertainties with previous estimates at z 10 from blank fields. The combination of these new results with all other estimates is also consistent with a rapidly declining SFRD in the 170 Myr from z 8 to z 10 as predicted by cosmological simulations and dark-matter halo evolution in ΛCDM. Once biases introduced by magnificationdependent completeness are accounted for, the full six cluster and parallel Frontier Field program will be an extremely powerful new data set to probe the evolution of the galaxy population at z 8 > before the advent of the James Webb Space Telescope.
