Tomography of the Cosmic Dawn and Reionization Eras with Multiple Tracers

Kavli Affiliate: Jacqueline Hewitt | First 5 Authors: Tzu-Ching Chang, Angus Beane, Olivier Dore, Adam Lidz, Lluis Mas-Ribas | Summary: The Cosmic Dawn and Reionization epochs remain a fundamental but challenging frontier of astrophysics and cosmology. We advocate a large-scale, multi-tracer approach to develop a comprehensive understanding of the physics that led to the formation […]

The Dynamic Infrared Sky

Kavli Affiliate: Rob Simcoe | First 5 Authors: Mansi M. Kasliwal, Scott Adams, Igor Andreoni, Michael Ashley, Nadia Blagorodnova | Summary: Opening up the dynamic infrared sky for systematic time-domain exploration would yield many scientific advances. Multi-messenger pursuits such as localizing gravitational waves from neutron star mergers and quantifying the nucleosynthetic yields require the infrared. […]

A close look at the dwarf AGN of NGC 4395: optical and near-IR integral field spectroscopy

Kavli Affiliate: Luis Ho | First 5 Authors: Carine Brum, Marlon R. Diniz, Rogemar A. Riffel, Alberto Rodriguez-Ardila, Luis Ho | Summary: Intermediate mass black holes (10$^3$-10$^5$ M$_odot$) in the center of dwarf galaxies are believed to be analogous to growing Active Galactic Nuclei (AGN) in the early Universe. Their characterization can provide insight about […]

Type-II Ising Pairing in Few-Layer Stanene

Kavli Affiliate: Joseph Falson | First 5 Authors: Joseph Falson, Yong Xu, Menghan Liao, Yunyi Zang, Kejing Zhu | Summary: Spin-orbit coupling has proven indispensable in realizing topological materials and more recently Ising pairing in two-dimensional superconductors. This pairing mechanism relies on inversion symmetry breaking and sustains anomalously large in-plane polarizing magnetic fields whose upper […]

Cosmology with the Highly Redshifted 21cm Line

Kavli Affiliate: Jacqueline Hewitt | First 5 Authors: Adrian Liu, James Aguirre, Yacine Ali-Haimoud, Marcelo Alvarez, Adam Beardsley | Summary: In addition to being a probe of Cosmic Dawn and Epoch of Reionization astrophysics, the 21cm line at $z>6$ is also a powerful way to constrain cosmology. Its power derives from several unique capabilities. First, […]

The Transiting Multi-planet System HD15337: Two Nearly Equal-mass Planets Straddling the Radius Gap

Kavli Affiliate: Robert Goeke | First 5 Authors: Davide Gandolfi, Luca Fossati, John H. Livingston, Keivan G. Stassun, Sascha Grziwa | Summary: We report the discovery of a super-Earth and a sub-Neptune transiting the star HD 15337 (TOI-402, TIC 120896927), a bright (V=9) K1 dwarf observed by the Transiting Exoplanet Survey Satellite (TESS) in Sectors […]

Mapping the Inner Structure of Quasars with Time-Domain Spectroscopy

Kavli Affiliate: Luis Ho | First 5 Authors: Yue Shen, Scott Anderson, Edo Berger, W. N. Brandt, Gisella De Rosa | Summary: The ubiquitous variability of quasars across a wide range of wavelengths and timescales encodes critical information about the structure and dynamics of the circumnuclear emitting regions that are too small to be directly […]
