Kavli Affiliate: Scott A. Hughes | First 5 Authors: Michael L. Katz, Alvin J. K. Chua, Lorenzo Speri, Niels Warburton, Scott A. Hughes | Summary: We present the FastEMRIWaveforms (FEW) package, a collection of tools to build and analyze extreme mass ratio inspiral (EMRI) waveforms. Here, we expand on the Physical Review Letter that introduced […]
Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Paul La Plante, Peter K. G. Williams, Matthew Kolopanis, Joshua S. Dillon, Adam P. Beardsley | Summary: As current- and next-generation astronomical instruments come online, they will generate an unprecedented deluge of data. Analyzing these data in real time presents unique conceptual and computational challenges, and […]
Kavli Affiliate: Edward H. Morgan | First 5 Authors: Jiayin Dong, Chelsea X. Huang, Rebekah I. Dawson, Daniel Foreman-Mackey, Karen A. Collins | Summary: Warm Jupiters — defined here as planets larger than 6 Earth radii with orbital periods of 8–200 days — are a key missing piece in our understanding of how planetary systems […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Anirudh Chiti, Anna Frebel, Mohammad K. Mardini, Tatsuya W. Daniel, Xiaowei Ou | Summary: The Milky Way’s metal-poor stars are nearby ancient objects that are used to study early chemical evolution and the assembly and structure of the Milky Way. Here we present reliable metallicities of $sim280,000$ […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Anirudh Chiti, Mohammad K. Mardini, Anna Frebel, Tatsuya Daniel, | Summary: We present a low metallicity map of the Milky Way consisting of $sim$111,000 giants with $-3.5 lesssim$ [Fe/H] $lesssim -$0.75, based on public photometry from the second data release of the SkyMapper survey. These stars extend […]
Kavli Affiliate: Roland K. Vanderspek | First 5 Authors: Teruyuki Hirano, John H. Livingston, Akihiko Fukui, Norio Narita, Hiroki Harakawa | Summary: We present observations of two bright M dwarfs (TOI-1634 and TOI-1685: $J=9.5-9.6$) hosting ultra-short period (USP) planets, identified by the TESS mission. The two stars are similar in temperature, mass, and radius ($T_mathrm{eff},approx,3500$ […]
Kavli Affiliate: Christopher J. Burke | First 5 Authors: Natalia M. Guerrero, S. Seager, Chelsea X. Huang, Andrew Vanderburg, Aylin Garcia Soto | Summary: We present 2,241 exoplanet candidates identified with data from the Transiting Exoplanet Survey Satellite (TESS) during its two-year prime mission. We list these candidates in the TESS Objects of Interest (TOI) […]
Kavli Affiliate: Erin Kara | First 5 Authors: Ann Zabludoff, Iair Arcavi, Stephanie La Massa, Hagai B. Perets, Benny Trakhtenbrot | Summary: Recent claimed detections of tidal disruption events (TDEs) in multi-wavelength data have opened potential new windows into the evolution and properties of otherwise dormant supermassive black holes (SMBHs) in the centres of galaxies. […]
Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Jianrong Tan, Adrian Liu, Nicholas S. Kern, Zara Abdurashidova, James E. Aguirre | Summary: Precise measurements of the 21 cm power spectrum are crucial for understanding the physical processes of hydrogen reionization. Currently, this probe is being pursued by low-frequency radio interferometer arrays. As these experiments […]
Kavli Affiliate: Erin Kara | First 5 Authors: Ryan-Rhys Griffiths, Jiachen Jiang, Douglas J. K. Buisson, Dan R. Wilkins, Luigi C. Gallo | Summary: The optical and UV variability of the majority of AGN may be related to the reprocessing of rapidly-changing X-ray emission from a more compact region near the central black hole. Such […]
