Entropy Enhanced Multi-Agent Coordination Based on Hierarchical Graph Learning for Continuous Action Space

Kavli Affiliate: Ke Wang | First 5 Authors: Yining Chen, Ke Wang, Guanghua Song, Xiaohong Jiang, | Summary: In most existing studies on large-scale multi-agent coordination, the control methods aim to learn discrete policies for agents with finite choices. They rarely consider selecting actions directly from continuous action spaces to provide more accurate control, which […]

Disentangled Representation with Causal Constraints for Counterfactual Fairness

Kavli Affiliate: Ke Wang | First 5 Authors: Ziqi Xu, Jixue Liu, Debo Cheng, Jiuyong Li, Lin Liu | Summary: Much research has been devoted to the problem of learning fair representations; however, they do not explicitly the relationship between latent representations. In many real-world applications, there may be causal relationships between latent representations. Furthermore, […]

The Photon Ring in M87*

Kavli Affiliate: Lijing Shao | First 5 Authors: Avery E. Broderick, Dominic W. Pesce, Paul Tiede, Hung-Yi Pu, Roman Gold | Summary: We report measurements of the gravitationally lensed secondary image — the first in an infinite series of so-called "photon rings" — around the supermassive black hole M87* via simultaneous modeling and imaging of […]

A Mid-infrared Flare in the Seyfert Galaxy NGC 3786: A Changing-look Event Triggered by an Obscured Tidal Disruption Event?

Kavli Affiliate: Luis C. Ho | First 5 Authors: Suyeon Son, Minjin Kim, Luis C. Ho, Dohyeong Kim, Taehyun Kim | Summary: We report an exceptional mid-infrared flare in the Seyfert 1.8 NGC 3786. In the multi-epoch data from the Wide-field Infrared Survey Explorer, the nuclear mid-infrared brightness of NGC 3786 appears to vary substantially […]

The JCMT Transient Survey: Single Epoch Transients and Variability of Faint Sources

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Doug Johnstone, Bhavana Lalchand, Steve Mairs, Hsien Shang, Wen Ping Chen | Summary: Short-duration flares at millimeter wavelengths provide unique insights into the strongest magnetic reconnection events in stellar coronae, and combine with longer-term variability to introduce complications to next-generation cosmology surveys. We analyze 5.5 years […]

Spectral extremal graphs for disjoint cliques

Kavli Affiliate: Jing Wang | First 5 Authors: Zhenyu Ni, Jing Wang, Liying Kang, , | Summary: The $kK_{r+1}$ is the union of $k$ disjoint copies of $(r+1)$-clique. Moon [Canad. J. Math. 20 (1968) 95–102] and Simonovits [Theory of Graphs (Proc. colloq., Tihany, 1996)] independently showed that if $n$ is sufficiently large, then $K_{k-1}vee T_{n-k+1,r}$ […]

The LSST era of supermassive black holes accretion-disk reverberation mapping

Kavli Affiliate: Claudio Ricci | First 5 Authors: Andjelka B. Kovacevic, Viktor Radovic, Dragana Ilic, Luka C. Popovic, Roberto J. Assef | Summary: The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) will detect an unprecedentedly large sample of actively accreting supermassive black holes with typical accretion disk (AD) sizes of a […]

Towards a comprehensive view of accretion, inner disks, and extinction in classical T Tauri stars: an ODYSSEUS study of the Orion OB1b association

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Caeley V. Pittman, Catherine C. Espaillat, Connor E. Robinson, Thanawuth Thanathibodee, Nuria Calvet | Summary: The coevolution of T Tauri stars and their surrounding protoplanetary disks dictates the timescales of planet formation. In this paper, we present magnetospheric accretion and inner disk wall model fits to […]

The Star-forming Main Sequence of the Host Galaxies of Low-redshift Quasars

Kavli Affiliate: Luis C. Ho | First 5 Authors: Ming-Yang Zhuang, Luis C. Ho, , , | Summary: We investigate the star-forming main sequence of the host galaxies of a large, well-defined sample of 453 redshift $sim$0.3 quasars with previously available star formation rates by deriving stellar masses from modeling their broad-band ($grizy$) spectral energy […]
