The Pantheon+ Analysis: Forward-Modeling the Dust and Intrinsic Colour Distributions of Type Ia Supernovae, and Quantifying their Impact on Cosmological Inferences

Posted by December 8, 2021Chicago

Kavli Affiliate: Richard Kessler | First 5 Authors: Brodie Popovic, Dillon Brout, Richard Kessler, Daniel Scolnic, | Summary: Recent studies have shown that the observed colour distributions of Type Ia SNe (SNIa) are well-described by a combination of distributions from dust and intrinsic colour. Here we present a new forward-modeling fitting method (Dust2Dust) to measure […]

Shock Revival in Core-collapse Supernovae Assisted by Heavy Axion-like Particles

Posted by klaurent December 7, 2021Tokyo

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Kanji Mori, Tomoya Takiwaki, Kei Kotake, Shunsaku Horiuchi, | Summary: Axion-like particles (ALPs) are a class of hypothetical pseudoscalar particles which feebly interact with ordinary matter. The hot plasma of core-collapse supernovae is a possible laboratory to explore physics beyond the standard model including ALPs. Once produced, […]

Benchmarking the performance of DFT functionals for absorption and fluorescence spectra of EGFR inhibitor AG-1478 using TD-DFT

Posted by klaurent December 7, 2021Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Sallam Alagawani, Vladislav Vasilyev, Feng Wang, , | Summary: Optical spectra (UV-vis and fluorescence) are sensitive to the chemical environment and conformation of fluorophores and therefore, are ideal probes for their conformation and solvent responses. Tyrosine kinase inhibitors (TKI) such as AG-1478 of epidermal growth factor receptor […]

Loopy Determinations of $V_{ub}$ and $V_{cb}$

Posted by December 7, 2021Caltech

Kavli Affiliate: Nathan Lewis | First 5 Authors: Wolfgang Altmannshofer, Nathan Lewis, , , | Summary: We use loop induced processes like meson oscillations and rare b hadron decays to determine the absolute values of the CKM matrix elements $|V_{ub}|$ and $|V_{cb}|$ and compare our results to the standard determinations based on inclusive and exclusive […]

Milli-Hertz Gravitational Wave Background Produced by Quasi-Periodic Eruptions

Posted by klaurent December 6, 2021Peking

Kavli Affiliate: Xian Chen | First 5 Authors: Xian Chen, Yu Qiu, Shuo Li, F. K. Liu, | Summary: Extreme-mass-ratio inspirals (EMRIs) are important targets for future space-borne gravitational-wave (GW) detectors, such as the Laser Interferometer Sapce Antenna (LISA). Recent works suggest that EMRI may reside in a population of newly discovered X-ray transients called […]

Using principal stratification in analysis of clinical trials

Posted by klaurent December 6, 2021Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Ilya Lipkovich, Bohdana Ratitch, Yongming Qu, Xiang Zhang, Mingyang Shan | Summary: The ICH E9(R1) addendum (2019) proposed principal stratification (PS) as one of five strategies for dealing with intercurrent events. Therefore, understanding the strengths, limitations, and assumptions of PS is important for the broad community of […]
