ALMA2040: Mapping the Spatially Resolved Dust and Star Formation Physics Driving High-z Galaxy Assembly
Daizhong Liu, Gergö Popping, Pierre Cox +19
Interstellar dust reprocesses approximately half of the starlight emitted across cosmic history. However, dust temperature, which is essential to convert continuum flux into dust m…
Dust at cosmic dawn: unveiling the onset of dust and obscured star formation at
Hiddo Algera, Tom Bakx, Manuel Aravena +31
Although less than 1 percent of the baryonic mass budget of a galaxy, cosmic dust profoundly alters the multi-wavelength appearance of galaxies across cosmic time. The (sub)millime…
The dawn of the first galaxies
Livia Vallini, Tanio Diaz Santos, Belen Alcalde Pampliega +56
Understanding how the first galaxies assembled their stellar mass at cosmic dawn is a central frontier of modern astrophysics. JWST has now revealed an unexpected population of ult…
Diverse ionized gas conditions in a dynamically hot, interacting galaxy at revealed by JWST/NIRSpec IFU
Ryota Ikeda, Takahiro Morishita, Massimo Stiavelli +1
We present a spatially and spectrally resolved study of an interacting galaxy, Gz9p3 at , using the James Webb Space Telescope NIRSpec/G395H IFU observation with high-spect…
Galactic Archaeology with the Subaru `Ōnohi`ula Prime Focus Spectrograph Strategic Program
Masashi Chiba, Rosemary F. G. Wyse, Evan N. Kirby +48
The recently commissioned Subaru `Ōnohi`ula Prime Focus Spectrograph (PFS) will obtain spectra from nearly 2,400 fibers that cover 1.24 square degrees. The 360 night Subaru Strateg…
ELPIS: Accelerated metal and dust enrichment in a proto-cluster core at
Hideki Umehata, Yoichi Tamura, Yoshinobu Fudamoto +17
We present a study of the metal, dust, and molecular gas content in galaxies within the A2744-z7p9OD proto-cluster at z ~ 7.88. We focus on two galaxy groups, the Quintet and the C…
Formation of Substructure in Luminous Submillimeter Galaxies (FOSSILS): Evidence of Multiple Pathways to Trigger Starbursts in Luminous Submillimeter Galaxies
Ryota Ikeda, Daisuke Iono, Ken-ichi Tadaki +19
We present an analysis of rest-frame optical and far-infrared continuum emission in three luminous submillimeter galaxies (SMGs) at . The SMGs are spatial…
A Potential Link between Nuclear Winds and Cold Gas Outflows on Kiloparsec Scales in Reionization-Era Quasars
Yongda Zhu, Marcia J. Rieke, Luis C. Ho +23
Feedback from accreting supermassive black holes may regulate galaxy evolution, but statistical evidence linking nuclear winds to kiloparsec-scale cold gas outflows remains limited…
ALMA detection of [OIII] 88um at z=12.33: Exploring the Nature and Evolution of GHZ2 as a Massive Compact Stellar System
Jorge A. Zavala, Tom Bakx, Ikki Mitsuhashi +21
We present ALMA observations on the high-redshift galaxy GHZ2 and report a successful detection of the rest-frame 88um atomic transition from doubly-ionized Oxygen at z=12.3327+/-0…
Discovery of a Unique Close Quasar-DSFG Pair Linked by a [C II] Bridge at

We report the discovery of a unique quasar-dusty star-forming galaxy (DSFG) system at , consisting of the bright quasar J1133+1603 () and its compact…
A luminous and young galaxy at z=12.33 revealed by a JWST/MIRI detection of Hα and [OIII]
Jorge A. Zavala, Marco Castellano, Hollis B. Akins +37
The James Webb Space Telescope (JWST) has discovered a surprising population of bright galaxies in the very early universe (<500 Myrs after the Big Bang) that is hard to explain wi…
