Impact of reionization history on constraining primordial gravitational waves in future all-sky cosmic microwave background experiments

Posted by dbos December 20, 2024January 13, 2025Tokyo

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Hanchun Jiang, Toshiya Namikawa, , , | Summary: We explore the impact of the reionization history on examining the shape of the power spectrum of the primordial gravitational waves (PGWs) with the cosmic microwave background (CMB) polarization. The large-scale CMB generated from the reionization epoch is important […]

Unveiling the Cosmic Chemistry II: “direct” $T_e$-based metallicity of galaxies at 3 $< z <$ 10 with JWST/NIRSpec

Posted by dbos December 19, 2024MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Priyanka Chakraborty, Arnab Sarkar, Randall Smith, Gary J. Ferland, Michael McDonald | Summary: We report the detection of the [O III] auroral line in 42 galaxies within the redshift range of $3 < z < 10$. These galaxies were selected from publicly available JWST data releases, including […]

Transcribing and Translating, Fast and Slow: Joint Speech Translation and Recognition

Posted by dbos December 19, 2024January 13, 2025Stanford

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Niko Moritz, Ruiming Xie, Yashesh Gaur, Ke Li, Simone Merello | Summary: We propose the joint speech translation and recognition (JSTAR) model that leverages the fast-slow cascaded encoder architecture for simultaneous end-to-end automatic speech recognition (ASR) and speech translation (ST). The model is transducer-based and uses a […]

Observational Signatures of Disk Winds in Protoplanetary Disks: Differentiating Magnetized and Photoevaporative Outflows With Fully Coupled Thermochemistry

Posted by dbos December 19, 2024January 13, 2025Peking

Kavli Affiliate: Lile Wang | First 5 Authors: Xiao Hu, Jaehan Bae, Zhaohuan Zhu, Lile Wang, | Summary: Magnetized winds and photoevaporative winds are critical in shaping protoplanetary disk evolution. Using 2D axisymmetric (magneto-)hydrodynamic simulations with Athena++ implementing fully coupled thermochemistry, we investigate the signatures of the two winds in CO and [C~I] ALMA observations, […]

Scattering theory of higher order topological phases

Posted by dbos December 19, 2024Delft

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: R. Johanna Zijderveld, Isidora Araya Day, Anton R. Akhmerov, , | Summary: The surface states of intrinsic higher order topological phases are protected by the spatial symmetries of a finite sample. This property makes the existing scattering theory of topological invariants inapplicable because the scattering geometry […]

The effects of different cooling and heating function models on a simulated analog of NGC300

Posted by dbos December 19, 2024January 13, 2025Chicago

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: David Robinson, Camille Avestruz, Nickolay Y. Gnedin, Vadim A. Semenov, | Summary: Gas cooling and heating rates are vital components of hydrodynamic simulations. However, they are computationally expensive to evaluate exactly with chemical networks or photoionization codes. We compare two different approximation schemes for gas cooling […]
