ALMA Spectroscopic Survey in the Hubble Ultra Deep Field: The Infrared Excess of UV-selected z=2-10 galaxies as a function of UV-continuum Slope and Stellar Mass
Rychard Bouwens,Manuel Aravena,Roberto Decarli,Fabian Walter,Fabian Walter,Elisabete da Cunha,Elisabete da Cunha,Ivo Labbé,Franz E. Bauer,Franz E. Bauer,Franz E. Bauer,Frank Bertoldi,Chris Carilli,Scott Chapman,Emanuele Daddi,Jacqueline Hodge,Rob Ivison,Rob Ivison,Alex Karim,Olivier Le Fevre,Benjamin Magnelli,Kazuaki Ota,Dominik Riechers,Ian Smail,Paul van der Werf,Axel Weiss,Pierre Cox,David Elbaz,Jorge González-López,Leopoldo Infante,Pascal Oesch,Jeff Wagg,S. Wilkins +32 more
TL;DR: In this paper, the authors make use of deep 1.2 mm continuum observations (12.7 μJy beam−1 rms) of a 1 arcmin² region in the Hubble Ultra Deep Field to probe dust-enshrouded star formation from 330 Lyman-break galaxies spanning the redshift range z = 2−10 (to ∼2-3 M⊙ yr−1 at 1σ over the entire range).

TL;DR: In this article, the authors present the rationale for and the observational description of ASPECS: the ALMA SPECtroscopic Survey in the Hubble Ultra-Deep Field (UDF), the cosmological deep field that has the deepest multi-wavelength data available.
Journal ArticleDOI

Akio K. Inoue,Yoichi Tamura,Hiroshi Matsuo,Ken Mawatari,Ikkoh Shimizu,Takatoshi Shibuya,Kazuaki Ota,Naoki Yoshida,Erik Zackrisson,Nobunari Kashikawa,Kotaro Kohno,Hideki Umehata,Hideki Umehata,Bunyo Hatsukade,Masanori Iye,Yuichi Matsuda,Takashi Okamoto,Yuki Yamaguchi +17 more
TL;DR: The Atacama Large Millimeter/submillimeter Array detection of an oxygen emission line at a wavelength of 88 micrometers from a galaxy at an epoch about 700 million years after the Big Bang is reported.
Journal ArticleDOI
The First Systematic Survey for Lyα Emitters at z = 7.3 with Red-sensitive Subaru/Suprime-Cam

TL;DR: In this article, a definitively asymmetric emission line is detected for one of them, SXDF-NB1006-2. Assuming this line is Lyα, this object is an LAE at z = 7.3.
