Revealing AGNs Through TESS Variability

Kavli Affiliate: Michael M. Fausnaugh | First 5 Authors: Helena P. Treiber, Jason T. Hinkle, Michael M. Fausnaugh, Benjamin J. Shappee, Christopher S. Kochanek | Summary: We used Transiting Exoplanet Survey Satellite (TESS) data to identify 29 candidate active galactic nuclei (AGNs) through their optical variability. The high-cadence, high-precision TESS light curves present a unique […]

Cosmic Reionization On Computers: Baryonic Effects on Halo Concentrations During the Epoch of Reionization

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Hanjue Zhu, Nickolay Y. Gnedin, , , | Summary: Baryons both increase halo concentration through adiabatic contraction and expel mass through feedback processes. However, it is not well understood how the radiation fields prevalent during the epoch of reionization affect the evolution of concentration in dark […]

An old warm Jupiter orbiting the metal-poor G-dwarf TOI-5542

Kavli Affiliate: Robert F. Goeke | First 5 Authors: Nolan Grieves, François Bouchy, Solène Ulmer-Moll, Samuel Gill, David R. Anderson | Summary: We report the discovery of a 1.32$^{+0.10}_{-0.10}$ $mathrm{M_{rm Jup}}$ planet orbiting on a 75.12 day period around the G3V $10.8^{+2.1}_{-3.6}$ Gyr old star TOI-5542 (TIC 466206508; TYC 9086-1210-1). The planet was first detected […]

MAXI J1820+070 X-ray spectral-timing reveals the nature of the accretion flow in black hole binaries

Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Tenyo Kawamura, Chris Done, Magnus Axelsson, Tadayuki Takahashi, | Summary: Black hole X-ray binaries in the low/hard states display significant broad-band (stochastic) variability on short time-scales (0.01-100 seconds), with a complex pattern of lags in correlated variability seen in different energy bands. This behaviour is generally interpreted […]

TESS spots a mini-neptune interior to a hot saturn in the TOI-2000 system

Kavli Affiliate: Andrew M. Vanderburg | First 5 Authors: Lizhou Sha, Andrew M. Vanderburg, Chelsea X. Huang, David J. Armstrong, Rafael Brahm | Summary: Hot jupiters (P < 10 d, M > 60 $mathrm{M}_oplus$) are almost always found alone around their stars, but four out of hundreds known have inner companion planets. These rare companions […]

Towards a nonperturbative construction of the $S$-matrix

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Brian Henning, Hitoshi Murayama, Francesco Riva, Jedidiah O. Thompson, Matthew T. Walters | Summary: We present a nonperturbative recipe for directly computing the $S$-matrix in strongly-coupled QFTs. The method makes use of spectral data obtained in a Hamiltonian framework and can be applied to a wide range […]

On ${mathcal N}=4$ supersymmetry enhancements in three dimensions

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Benjamin Assel, Yuji Tachikawa, Alessandro Tomasiello, , | Summary: We introduce a class of 3d theories consisting of strongly-coupled ${mathcal N}=4$ systems coupled to ${mathcal N}=3$ Chern-Simons gauge multiplets, which exhibit ${mathcal N}=4$ enhancements when a peculiar condition on the Chern-Simons levels is met. An example is […]

Validation of TOI-1221 b, a warm sub-Neptune exhibiting TTVs around a Sun-like star

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Christopher R. Mann, David Lafrenière, Diana Dragomir, Samuel N. Quinn, Thiam-Guan Tan | Summary: We present a successful validation of the long-period ($91.68278^{+0.00032}_{-0.00041}$ days) transiting sub-Neptune planet TOI-1221 b (TIC 349095149.01) around a Sun-like (m$_{rm V}$=10.5) star. We combine {it TESS} light curve measurements and ground-based time-series […]
