Substructure at High Speed II: The Local Escape Velocity and Milky Way Mass with Gaia DR2

Kavli Affiliate: Lina Necib | First 5 Authors: Lina Necib, Tongyan Lin, , , | Summary: Measuring the escape velocity of the Milky Way is critical in obtaining the mass of the Milky Way, understanding the dark matter velocity distribution, and building the dark matter density profile. In Necib $&$ Lin (2021), we introduced a […]

Improved Spatial Resolution Achieved by Chromatic Intensity Interferometry

Kavli Affiliate: Frank Wilczek | First 5 Authors: Lu-Chuan Liu, Luo-Yuan Qu, Cheng Wu, Jordan Cotler, Fei Ma | Summary: Interferometers are widely used in imaging technologies to achieve enhanced spatial resolution, but require that the incoming photons be indistinguishable. In previous work, we built and analyzed color erasure detectors which expand the scope of […]

Eclipsing Binary Populations across the Northern Galactic Plane from the KISOGP survey

Kavli Affiliate: Huawei Zhang | First 5 Authors: Fangzhou Ren, Richard de Grijs, Huawei Zhang, Licai Deng, Xiaodian Chen | Summary: We present a catalog of eclipsing binaries in the northern Galactic Plane from the Kiso Wide-Field Camera Intensive Survey of the Galactic Plane (KISOGP). We visually identified 7055 eclipsing binaries spread across $sim$330 square […]

Improved Treatment of Host-Galaxy Correlations in Cosmological Analyses With Type Ia Supernovae

Kavli Affiliate: Richard Kessler | First 5 Authors: Brodie Popovic, Dillon Brout, Richard Kessler, Dan Scolnic, Lisa Lu | Summary: Improving the use of Type Ia supernovae (SNIa) as standard candles requires a better approach to incorporate the relationship between SNIa and the properties of their host galaxies. Using a spectroscopically-confirmed sample of $sim$1600 SNIa, […]

Measuring solar neutrinos over Gigayear timescales with Paleo Detectors

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Natalia Tapia Arellano, Shunsaku Horiuchi, , , | Summary: Measuring the solar neutrino flux over gigayear timescales could provide a new window to inform the Solar Standard Model as well as studies of the Earth’s long-term climate. We demonstrate the feasibility of measuring the time-evolution of the […]

Substructure at High Speed I: Inferring the Escape Velocity in the Presence of Kinematic Substructure

Kavli Affiliate: Lina Necib | First 5 Authors: Lina Necib, Tongyan Lin, , , | Summary: The local escape velocity provides valuable inputs to the mass profile of the Galaxy, and requires understanding the tail of the stellar speed distribution. Following Leonard $&$ Tremaine (1990), various works have since modeled the tail of the stellar […]

“A more probable explanation” is still impossible to explain GN-z11-flash: in response to Steinhardt et al. (arXiv:2101.12738)

Kavli Affiliate: Linhua Jiang | First 5 Authors: Linhua Jiang, Shu Wang, Bing Zhang, Nobunari Kashikawa, Luis C. Ho | Summary: In Jiang et al. (2020), we reported a possible bright flash (hereafter GN-z11-flash) from a galaxy GN-z11 at z ~ 11. Recently, Steinhardt et al. (2021; arXiv:2101.12738) found 27 images with transient signals in […]

Cosmological cross-correlations and nearest neighbor distributions

Kavli Affiliate: Tom Abel | First 5 Authors: Arka Banerjee, Tom Abel, , , | Summary: Cross-correlations between datasets are used in many different contexts in cosmological analyses. Recently, $k$-Nearest Neighbor Cumulative Distribution Functions ($k{rm NN}$-${rm CDF}$) were shown to be sensitive probes of cosmological (auto) clustering. In this paper, we extend the framework of […]
