Anatomy of a z=6 Lyman-α emitter down to parsec scales: extreme UV slopes, metal-poor regions and possibly leaking star clusters

Matteo Messa, E. Vanzella, F. Loiacono +31

We present a detailed JWST/NIRSpec and NIRCam analysis of a gravitationally-lensed galaxy () at redshift 6.14 magnified by the Hubble Frontier Field galaxy cluster MA…

The SCUBA-2 Cosmology Legacy Survey: 850um maps, catalogues and number counts

J. E. Geach, J. S. Dunlop, M. Halpern +66

We present a catalogue of nearly 3,000 submillimetre sources detected at 850um over ~5 square degrees surveyed as part of the James Clerk Maxwell Telescope (JCMT) SCUBA-2 Cosmology…

The ultracool eld dwarfs luminosity function from the Canada-France Brown Dwarf Survey

C. Reyle, P. Delorme, X. Delfosse +4

The Canada-France Brown Dwarf Survey is a wide eld survey for cool brown dwarfs conducted with the MegaCam camera on the CFHT telescope. Our objectives are to nd ultracool brown dw…

A robust morphological classification of high-redshift galaxies using support vector machines on seeing limited images. II. Quantifying morphological k-correction in the COSMOS field at 1<z<2: Ks band vs. I band

M. Huertas-Company, L. Tasca, D. Rouan +10

We quantify the effects of \emph{morphological k-correction} at by comparing morphologies measured in the K and I-bands in the COSMOS area. Ks-band data have indeed the adv…

Extreme Ionizing Properties of Metal-Poor, Muv ~ -12 Star Complex in the first Gyr

E. Vanzella, F. Loiacono, M. Messa +38

We report the serendipitous discovery of a faint (M_UV > -12.2), low-metallicity (Z ~ 0.02 Zsun), ionizing source (dubbed T2c) with a spectroscopic redshift of z=6.146. T2c is part…

JWST Reveals Two Overmassive Black Hole Candidates in Dwarf Galaxies at z 0.7: Pushing Black Hole Searches into the Dwarf-Galaxy Regime

E. Iani, P. Rinaldi, A. Torralba +35

We report the discovery and characterization of two compact galaxies, Pelias and Neleus, at z ~ 0.71 and z ~ 0.75, identified in MACS J0416.1-2403 and GOODS-North. Both exhibit unu…
