Decoupling the AGN outflow and star-forming disk kinematics in the nuclear region of NGC 7582 with JWST NIRSpec and MIRI/MRS

Posted by klaurent Peking

Kavli Affiliate: Claudio Ricci | Summary:We present a detailed study of the inner regions of NGC~7582, a nearby Seyfert~2 galaxy, from the Galaxy Activity, Torus and Outflow Survey (GATOS). The galaxy hosts a circumnuclear star-forming disk and an AGN-driven biconical ionised outflow. Using JWST NIRSpec and MIRI/MRS integral-field spectroscopy, we analyse ionic emission lines spanning […]

Singlet-triplet oscillations in multivalley Si double quantum dots

Posted by klaurent Delft

Kavli Affiliate: Giordano Scappucci | Summary:Charge separation from the $(4,0)$ to the $(3,1)$ state in a Si/SiGe double quantum dot is commonly used for initialization of spin qubits and Pauli-spin-blockade readout. It was used in recent experiments involving creation of the $(3,1)$ singlet, and subsequent shuttling of one of the electrons. We present a theoretical […]

Probing the Hot Gaseous Halos of Milky Way-like Galaxies in the TNG50 simulation

Posted by klaurent MIT

Kavli Affiliate: Mark Vogelsberger | Summary:The origin and structure of the hot ($Tgtrsim10^6$K) gaseous halo around Milky Way (MW)-mass galaxies provide a critical test for galaxy formation models. We perform a comprehensive comparison for a sample of MW analogues from the TNG50 cosmological simulation by generating synthetic soft X-ray emission and O VII/O VIII absorption […]

CSST Preparations: Galaxy Completeness and Sérsic Profile Fitting across the Wide, Deep, and Extreme Fields

Posted by klaurent Peking

Kavli Affiliate: Luis Ho | Summary:The upcoming imaging survey of the Chinese Space-station Survey Telescope (CSST) will deliver high-resolution imaging of an unprecedented number of galaxies for galaxy studies. To understand CSST’s capability, and to support the preparation of early-science programs, we generate 470,526 mock CSST images for 22,406 simulated galaxies with $M_*>10^9 M_odot$, whose […]

The long-term outburst(s) of GPSV16: from an intermediate to a FUor classification

Posted by klaurent Peking

Kavli Affiliate: Gregory Herczeg | Summary:FU Ori outbursts are thought to play a key role in stellar mass assembly and in the chemistry of protoplanetary disks during the early formation of stars. However, uncertainties remain regarding the universality of these events and the physical mechanism driving the high-amplitude variability. In this work, we present an […]

SVOM/VT: Real-Time Onboard Data Processing

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao| Summary:The SVOM Visible Telescope (VT) is critical for the rapid identification of gamma-ray burst (GRB) optical counterparts, particularly for high-redshift candidates that require immediate infrared spectroscopic follow-up. To address the stringent bandwidth constraints of the VHF downlink while ensuring real-time data availability, we developed the VT Onboard Data Processing Pipeline (VOPP).This […]

SVOM/VT: Flight Model Verification and Pre-launch Testing

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao| Summary:This paper presents pre-launch testing and calibration results for the SVOM/VT (Space-based Variable Objects Monitor, Visible Telescope) Flight Model (FM), validating its performance under simulated space conditions through thermal vacuum cycling, energy concentration analysis, stray light suppression, and CCD/electronics calibrations (gain, noise, quantum efficiency). The results confirm full compliance with design […]
