INSPIRE: INvestigating Stellar Population In RElics -- VII. The local environment of ultra-compact massive galaxies

Diana Scognamiglio, Chiara Spiniello, Mario Radovich +15

Relic galaxies, the oldest ultra-compact massive galaxies (UCMGs), contain almost exclusively "pristine" stars formed during an intense star formation (SF) burst at high redshift.…

Nonlinear stability threshold for compressible Couette flow

Feimin Huang, Rui Li, Lingda Xu

This paper concerns the Couette flow for 2-D compressible Navier-Stokes equations (N-S) in an infinitely long flat torus $\Torus\times\R$. Compared to the incompressible flow, the…

Velocity-Resolved Ionization Mapping of Broad Line Region. I. Insights into Diverse Geometry and Kinematics

Sha-Sha Li, Hai-Cheng Feng, H. T. Liu +6

Broad emission lines of active galactic nuclei (AGNs) originate from the broad-line region (BLR), consisting of dense gas clouds in orbit around an accreting supermassive black hol…

DenseLens -- Using DenseNet ensembles and information criteria for finding and rank-ordering strong gravitational lenses,

Bharath Chowdhary Nagam, Léon V. E. Koopmans, Edwin A. Valentijn +5

Convolutional neural networks (CNNs) are the state-of-the-art technique for identifying strong gravitational lenses. Although they are highly successful in recovering genuine lens…

Discovering strongly lensed quasar candidates with catalogue-based methods from DESI Legacy Surveys

Zizhao He, Nan Li, Xiaoyue Cao +3

The Hubble tension, revealed by a discrepancy between measurements of the Hubble-Lemaitre constant from early- and local-Universe observations, is one of the most signifi…

Velocity-resolved Reverberation Mapping of Changing-look Active Galactic Nucleus NGC~4151 During Outburst Stage: Evidence for Kinematics Evolution of Broad-line Region

Sha-Sha Li, Hai-Cheng Feng, H. T. Liu +6

Changing-look active galactic nucleus NGC~4151, which has attracted a lot of attention, is undergoing the second dramatic outburst stage in its evolutionary history. To investigate…
