Kavli Affiliate: Dheeraj Pasham | First 5 Authors: Yukta Ajay, Muryel Guolo, Dheeraj Pasham, , | Summary: We present multiwavelength analyses of an active optical transient AT2021fxu which shows the appearance of previously absent broad emission lines in a recent optical spectrum, suggesting a Changing-look (CL) Active Galactic Nucleus (AGN). During the spectral transition, the […]
Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Jiawen Fan, Hanjue Zhu, Camille Avestruz, Nickolay Y. Gnedin, | Summary: Lyman limit systems (LLSs) are dense hydrogen clouds with high enough HI column densities to absorb Lyman continuum photons emitted from distant quasars. Their high column densities imply an origin in dense environments; however, the […]

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Yunchong Zhang, Viraj Manwadkar, Michael D. Gladders, Gourav Khullar, Håkon Dahle | Summary: We report the discovery of five bright strong gravitationally lensed galaxies at $3 < z < 4$: COOLJ0101$+$2055 ($z = 3.459$), COOLJ0104$-$0757 ($z = 3.480$), COOLJ0145$+$1018 ($z = 3.310$), COOLJ0516$-$2208 ($z = 3.549$), […]
Philip F. Hopkins, Ethan O. Nadler, Michael Y. Grudic, Xuejian Shen, Isabel Sands | Summary: [[{“value”:”Modeling self-gravity of collisionless fluids (e.g. ensembles of dark matter, stars, black holes, dust, planetary bodies) in simulations is challenging and requires some force softening. It is often desirable to allow softenings to evolve adaptively, in any high-dynamic range simulation, […]

Kavli Affiliate: Andrei Faraon | First 5 Authors: James Ang, Gabriella Carini, Yanzhu Chen, Isaac Chuang, Michael Austin DeMarco | Summary: Many proposals to scale quantum technology rely on modular or distributed designs where individual quantum processors, called nodes, are linked together to form one large multinode quantum computer (MNQC). One scalable method to construct […]

Kavli Affiliate: Gary A. Steele | First 5 Authors: Byoung-moo Ann, Sercan Deve, Gary A. Steele, , | Summary: Microwave driving is a ubiquitous technique for superconducting qubits (SCQs), but the dressed states description based on the conventionally used perturbation theory cannot fully capture the dynamics in the strong driving limit. Comprehensive studies beyond these […]
