Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Barry F. Madore, Wendy L. Freedman Kayla A. Owens, In Sung Jang, , | Summary: We present an extensive grid of numerical simulations quantifying the uncertainties in measurements of the Tip of the Red Giant Branch (TRGB). These simulations incorporate a luminosity function composed of 2 […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Xuejian Shen, Mark Vogelsberger, Michael Boylan-Kolchin, Sandro Tacchella, Rahul Kannan | Summary: JWST observations have revealed a population of galaxies bright enough that potentially challenge standard galaxy formation models in the $Lambda$CDM cosmology. Using a minimal empirical framework, we investigate the influence of variability on the rest-frame […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Zhen Cao, F. Aharonian, Q. An, Axikegu, Y. X. Bai | Summary: The diffuse Galactic $gamma$-ray emission, mainly produced via interactions between cosmic rays and the diffuse interstellar medium, is a very important probe of the distribution, propagation, and interaction of cosmic rays in the Milky […]

In this work […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Mohammad K. Mardini, Anna Frebel, Leyatt Betre, Heather Jacobson, John E. Norris | Summary: Based on high-resolution spectra obtained with Magellan/MIKE, we present a chemo-dynamical analysis for 27 near main-sequence turnoff metal-poor stars, including 20 stars analyzed for the first time. The sample spans a range in […]
Shengqi Yang, Fangzhou Jiang, Andrew Benson, Yi-Ming Zhong, Charlie Mace | Summary: [[{“value”:”One necessary step for probing the nature of self-interacting dark matter (SIDM) particles with astrophysical observations is to pin down any possible velocity dependence in the SIDM cross section. Major challenges for achieving this goal include eliminating, or mitigating, the impact of the […]

Kavli Affiliate: Xian Chen | First 5 Authors: Han Yan, Xian Chen, Alejandro Torres-Orjuela, , | Summary: The possibility of forming gravitational-wave sources with high center-of-mass (c.m.) velocities in the vicinity of supermassive black holes requires us to develop a method of deriving the waveform in the observer’s frame. Here we show that in the […]
