Cosmological distance forecasts for the CSST Galaxy Survey using BAO peaks

Kavli Affiliate: Hu Zhan | First 5 Authors: Feng Shi, Jieyi Tian, Zhejie Ding, Xiaohu Yang, Yizhou Gu | Summary: The measurement of cosmological distances using baryon acoustic oscillations (BAO) is crucial for studying the universe’s expansion. The Chinese Space Station Telescope (CSST) galaxy redshift survey, with its vast volume and sky coverage, provides an […]

Cross-correlating the patchy screening and kinetic Sunyaev-Zel’dovich effects as a new probe of reionization

Kavli Affiliate: Blake Sherwin | First 5 Authors: Darby Kramer, Alexander van Engelen, Christopher Cain, Niall MacCrann, Hy Trac | Summary: The kinetic Sunyaev-Zel’dovich effect (kSZ) and patchy screening effect are two complementary cosmic microwave background (CMB) probes of the reionization era. The kSZ effect is a relatively strong signal, but is difficult to disentangle […]

The Guitar’s Magnetic Field Revealed by Starlight Polarization

Kavli Affiliate: Roger W. Romani | First 5 Authors: Jack T. Dinsmore, Roger W. Romani, , , | Summary: The Guitar nebula surrounding PSR B2224+65 boasts a pulsar X-ray filament likely aligned with the local magnetic field. We present new RoboPol stellar polarization data distributed along the line-of-sight to the pulsar. The polarizing effect of […]

The I-Love universal relation for polytropic stars under Newtonian gravity

Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Rui Xu, Alejandro Torres-Orjuela, Lars Andersson, Pau Amaro Seoane, | Summary: The moment of inertia and tidal deformability of idealized stars with polytropic equations of state (EOSs) are numerically calculated under both Newtonian gravity and general relativity (GR). The results explicitly confirm that the relation between […]

The diverse physical origins of stars in the dynamically hot bulge: CALIFA vs. IllustrisTNG

Le Zhang, Ling Zhu, Annalisa Pillepich, Min Du, Fangzhou Jiang | Summary: [[{“value”:”We compare the internal stellar structures of central galaxies in the TNG50 and TNG100 simulations and field galaxies in the CALIFA survey. The luminosity fractions of the dynamically cold, warm, and hot components in both TNG50 and TNG100 galaxies exhibit general consistency with […]

Long-lived Habitable Zones around White Dwarfs undergoing Neon-22 Distillation

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Andrew Vanderburg, Antoine Bédard, Juliette C. Becker, Simon Blouin, | Summary: White dwarf stars have attracted considerable attention in the past 15 years as hosts for potentially habitable planets, but their low luminosity and continuous cooling are major challenges for habitability. Recently, astronomers have found that about […]

LensNet: Enhancing Real-time Microlensing Event Discovery with Recurrent Neural Networks in the Korea Microlensing Telescope Network

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Javier Viaña, Kyu-Ha Hwang, Zoë de Beurs, Jennifer C. Yee, Andrew Vanderburg | Summary: Traditional microlensing event vetting methods require highly trained human experts, and the process is both complex and time-consuming. This reliance on manual inspection often leads to inefficiencies and constrains the ability to scale […]

An Exceptionally Powerful, Radiatively Driven Ultrafast Outflow in the Rapidly Accreting AGN REJ1034+396

Kavli Affiliate: Steven Allen | First 5 Authors: Chloe Taylor, Daniel Wilkins, Steven Allen, , | Summary: We report the analysis of ~1Ms of XMM-Newton observations of the rapidly accreting active galactic nucleus REJ1034+396. The 0.3-9 keV EPIC-pn spectra are well described by a model consisting of steep continuum emission from the corona accompanied by […]
