Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Lauren Street, Nickolay Y. Gnedin, L. C. R. Wijewardhana, , | Summary: We perform maximum likelihood estimates (MLEs) for single and double flavor ultralight dark matter (ULDM) models using the Spitzer Photometry and Accurate Rotation Curves (SPARC) database. These estimates are compared to MLEs for several […]
Kavli Affiliate: Ke Wang | First 5 Authors: Wenhui Ren, Weikang Li, Shibo Xu, Ke Wang, Wenjie Jiang | Summary: Quantum computing promises to enhance machine learning and artificial intelligence. Different quantum algorithms have been proposed to improve a wide spectrum of machine learning tasks. Yet, recent theoretical works show that, similar to traditional classifiers […]
Kavli Affiliate: Salvatore Vitale | First 5 Authors: Sylvia Biscoveanu, Thomas A. Callister, Carl-Johan Haster, Ken K. Y. Ng, Salvatore Vitale | Summary: The population-level distributions of the masses, spins, and redshifts of binary black holes (BBHs) observed using gravitational waves can shed light on how these systems form and evolve. Because of the complex […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Qiuhong Shen, Lei Qiao, Jinyang Guo, Peixia Li, Xin Li | Summary: Unsupervised learning has been popular in various computer vision tasks, including visual object tracking. However, prior unsupervised tracking approaches rely heavily on spatial supervision from template-search pairs and are still unable to track objects […]
Kavli Affiliate: Salvatore Vitale | First 5 Authors: Salvatore Vitale, Sylvia Biscoveanu, Colm Talbot, , | Summary: It is expected that the orbital planes of gravitational-wave (GW) sources are isotropically distributed. However, both physical and technical factors, such as alternate theories of gravity with birefringence, catalog contamination, and search algorithm limitations, could result in inferring […]
Kavli Affiliate: David A. Principe | First 5 Authors: Joel H. Kastner, David A. Principe, , , | Summary: The past two decades have seen dramatic progress in our knowledge of the population of stars of age $lesssim$150 Myr that lie within $sim$100 pc of the Sun. Most such stars are found in loose kinematic […]

Kavli Affiliate: Ran Wang | First 5 Authors: Jianan Li, Bram P. Venemans, Fabian Walter, Roberto Decarli, Ran Wang | Summary: We present high spatial resolution (0.4", 2.2kpc) observations of the CO(6-5), CO(7-6) and [CI] lines and dust continuum emission from the interstellar medium in the host galaxy of the quasar J0305$-$3150 at $z=6.6$. These, […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Fabian Zimmer, Oscar Macias, Shin’ichiro Ando, Roland M. Crocker, Shunsaku Horiuchi | Summary: Since the discovery of an excess in gamma rays in the direction of M31, its cause has been unclear. Published interpretations focus on a dark matter or stellar related origin. Studies of a similar […]
Kavli Affiliate: Brian Nord | First 5 Authors: Kamilė Lukošiūtė, Geert Raaijmakers, Zoheyr Doctor, Marcelle Soares-Santos, Brian Nord | Summary: Detailed radiative transfer simulations of kilonova spectra play an essential role in multimessenger astrophysics. Using the simulation results in parameter inference studies requires building a surrogate model from the simulation outputs to use in algorithms […]
