Kavli Affiliate: Claudio Ricci | First 5 Authors: Ryan W. Pfeifle, Peter G. Boorman, Kimberly A. Weaver, Johannes Buchner, Francesca Civano | Summary: A fundamental goal of modern-day astrophysics is to understand the connection between supermassive black hole (SMBH) growth and galaxy evolution. Merging galaxies offer one of the most dramatic channels for galaxy evolution […]
Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Barry F. Madore, Wendy L. Freedman, Kayla Owens, , | Summary: Given the recent successful launch of the James Webb Space Telescope, determining robust calibrations of the slopes and absolute magnitudes of the near- to mid-infrared Tip of the Red Giant Branch (TRGB) will be essential […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Daniel M. Krolikowski, Adam L. Kraus, Benjamin M. Tofflemire, Caroline V. Morley, Andrew W. Mann | Summary: Young exoplanets trace planetary evolution, particularly the atmospheric mass loss that is most dynamic in youth. However, the high activity level of young stars can mask or mimic the spectroscopic […]
Kavli Affiliate: Melania Nynka | First 5 Authors: Kaya Mori, Gabriele Ponti, Matteo Bachetti, Arash Bodaghee, Jonathan Grindlay | Summary: HEX-P is a probe-class mission concept that will combine high spatial resolution X-ray imaging ($<10"$ FWHM) and broad spectral coverage (0.2-80 keV) with an effective area far superior to current facilities’ (including XMM-Newton and NuSTAR). […]
Kavli Affiliate: Ran Wang | First 5 Authors: Ran Wang, Raman Goyal, Suman Chakravorty, , | Summary: This paper studies the learning-to-control problem under process and sensing uncertainties for dynamical systems. In our previous work, we developed a data-based generalization of the iterative linear quadratic regulator (iLQR) to design closed-loop feedback control for high-dimensional dynamical […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Francesca Civano, Xiurui Zhao, Peter Boorman, Stefano Marchesi, Tonima Ananna | Summary: Since the discovery of the Cosmic X-ray Background, astronomers have strived to understand the accreting super massive black holes contributing to its peak in the 10-40 keV band. Existing soft X-ray telescopes could study this […]

Existing soft X-ray telescopes could study […]
Kavli Affiliate: Melania Nynka | First 5 Authors: Stephen Reynolds, Hongjun An, Moaz Abdelmaguid, Jason Alford, Chris L. Fryer | Summary: HEX-P is a probe-class mission concept that will combine high spatial resolution X-ray imaging ($<10"$ full width at half maximum) and broad spectral coverage (0.2–80 keV) with an effective area far superior to current […]
