Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Stuart Robert Anderson, Steven Gough-Kelly, Victor P. Debattista, Min Du, Peter Erwin | Summary: From the TNG50 cosmological simulation we build a sample of 191 well-resolved barred galaxies with a stellar mass $log M_star > 10$ at $z=0$. We search for box/peanut bulges (BPs) in this sample, […]
Kavli Affiliate: Erin A. Kara | First 5 Authors: Y. Homayouni, Gisella De Rosa, Rachel Plesha, Gerard A. Kriss, Aaron J. Barth | Summary: We present reverberation mapping measurements for the prominent ultraviolet broad emission lines of the active galactic nucleus Mrk817 using 165 spectra obtained with the Cosmic Origins Spectrograph on the Hubble Space […]

Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Pragati Pradhan, Carlo Ferrigno, Biswajit Paul, Enrico Bozzo, Ileyk El Mellah | Summary: Winds of massive stars are suspected to be inhomogeneous (or clumpy), which biases the measures of their mass loss rates. In High Mass X-ray Binaries (HMXBs), the compact object can be used as an […]

Kavli Affiliate: Robert F. Goeke | First 5 Authors: Melissa J. Hobson, Andrés Jordán, E. M. Bryant, R. Brahm, D. Bayliss | Summary: We present the discovery of TOI-3235 b, a short-period Jupiter orbiting an M-dwarf with a stellar mass close to the critical mass at which stars transition from partially to fully convective. TOI-3235 […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Anna Frebel, Alexander P. Ji, , , | Summary: This chapter presents an overview of the recent progress on spectroscopic observations of metal-poor stars with r-process element signatures found in the Milky Way’s stellar halo and satellite dwarf galaxies. Major empirical lessons related to the origins of […]
Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Pascal M. Keller, Bojan Nikolic, Nithyanandan Thyagarajan, Chris L. Carilli, Gianni Bernardi | Summary: Radio interferometers aiming to measure the power spectrum of the redshifted 21 cm line during the Epoch of Reionisation (EoR) need to achieve an unprecedented dynamic range to separate the weak signal […]

Kavli Affiliate: Gregory Prigozhin | First 5 Authors: Tanmoy Chattopadhyay, Sven Herrmann, Matthew Kaplan, Peter Orel, Kevan Donlon | Summary: The Single electron Sensitive Read Out (SiSeRO) is a novel on-chip charge detector output stage for charge-coupled device (CCD) image sensors. Developed at MIT Lincoln Laboratory, this technology uses a p-MOSFET transistor with a depleted […]
