Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Ke Wang, , , | Summary: The Schr"odinger-Poisson (SP) equations predict fuzzy dark matter (FDM) solitons. Given the FDM mass $sim10^-20rm~eV/c^2$, the FDM soliton in the Milky Way is massive $sim 10^7~M_odot$ but diffuse $sim 10rm~pc$. Therefore, this FDM soliton can serve as a gravitational […]
Kavli Affiliate: Saul A. Rappaport | First 5 Authors: Tajan H. de Amorim, Tajan H. de Amorim, , , | Summary: With its two stellar eclipses and two disk attenuations per binary orbit, V658 Carinae stands out as the first clear eclipsing Be + sdOB system. This rare alignment offers a unique opportunity to probe […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Haojie Xia, Haojie Xia, , , | Summary: We investigate the synchrotron emission signatures of shocks driven by active galactic nucleus (AGN) wind in elliptical galaxies based on our two-dimensional axisymmetric hydrodynamic $textitMACER$ numerical simulations. Using these simulation data, we calculate the synchrotron radiation produced by nonthermal […]
Kavli Affiliate: Subo Dong | First 5 Authors: B. JoHantgen, B. JoHantgen, , , | Summary: Dipper stars are extrinsically variable stars with deep dimming events due to extended, often dusty, structures produced by a wide range of mechanisms such as collisions, protoplanetary evolution or stellar winds. ASAS-SN has discovered 12 dipper-like objects as part […]
Kavli Affiliate: Aaron Roodman | First 5 Authors: Riley Clarke, Riley Clarke, , , | Summary: We present the first derivation of a stellar flare temperature profile from single-band photometry. Stellar flare DWF030225.574-545707.45129 was detected in 2015 by the Dark Energy Camera as part of the Deeper, Wider, Faster Programme. The brightness ($Delta m_g = […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Enrique Lopez-Rodriguez, Enrique Lopez-Rodriguez, , , | Summary: The polar mid-infrared (MIR) emission detected from tens to hundreds of parsecs in some active galactic nuclei (AGN) has been associated with dusty winds driven away by radiation pressure. However, the physical characterization of this extended polar emission remains […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: , , , , | Summary: Young exoplanets provide a critical link between understanding planet formation and atmospheric evolution. Direct imaging spectroscopy allows us to infer the properties of young, wide orbit, giant planets with high signal-to-noise. This allows us to compare this young population to exoplanets […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Wenbin Zhao, Wenbin Zhao, , , | Summary: We study particle correlations in high energy jets by comparing the measured energy-energy correlator (EEC) with that constructed from two individual energy flows with respect to the jet axis. This comparison demonstrates that genuine correlations exists for small angle […]
Kavli Affiliate: Masahiro Takada | First 5 Authors: Taisei Terawaki, Taisei Terawaki, , , | Summary: Galaxy-galaxy weak lensing provides a powerful means of measuring the average matter distribution around lens galaxies — i.e., the galaxy bias relation. Properly accounting for the spin-2 nature of weak lensing distortions, we develop a quadratic estimator for measuring […]
Kavli Affiliate: Katrin Heitmann | First 5 Authors: Stephen A. Walsh, Stephen A. Walsh, , , | Summary: Understanding the structure of our universe and the distribution of matter is an area of active research. As cosmological surveys grow in complexity, the development of emulators to efficiently and effectively predict matter power spectra is essential. […]
