Spectroscopic Characterization of Interstellar Object 3I/ATLAS: Water Ice in the Coma
Bin Yang, Karen J. Meech, Michael Connelley +2
We present optical and near-infrared spectroscopy of the interstellar object 3I/ATLAS, obtained with Gemini-S/GMOS and NASA IRTF/SpeX on 2025 July 5 and July 14. The optical spectr…
Detecting Early and Implicit Suicidal Ideation via Longitudinal and Information Environment Signals on Social Media
Soorya Ram Shimgekar, Ruining Zhao, Agam Goyal +5
On social media, several individuals experiencing suicidal ideation (SI) do not disclose their distress explicitly. Instead, signs may surface indirectly through everyday posts or…
Dust Extinction towards the Type Ia Supernova 2012cu in NGC 4772
Weijia Gao, Ruining Zhao, Jian Gao +2
Using photometric and spectroscopic data of Supernova (SN) 2012cu, a fairly reddened type Ia supernova, we derived its color excess curves and probed the dust extinction in its hos…
Dust and Volatiles in the Disintegrating Comet C/2019 Y4 (ATLAS)
Ruining Zhao, Aigen Li, Bin Yang +4
C/2019 Y4 (ATLAS) is an Oort cloud comet with an orbital period of 5895. Starting in March 2020, its nucleus underwent disintegration. In order to investigate the…
Deep-Learning continuous gravitational waves
Christoph Dreissigacker, Rahul Sharma, Chris Messenger +2
We present a first proof-of-principle study for using deep neural networks (DNNs) as a novel search method for continuous gravitational waves (CWs) from unknown spinning neutron st…
Post-Perihelion Integral Field Spectroscopy of the Interstellar Comet 3I/ATLAS
Willem B. Hoogendam, David O. Jones, Bin Yang +10
The environs of other stellar systems may be directly probed by analyzing the cometary activity of interstellar objects. The recently discovered interstellar object 3I/ATLAS was th…
Post-perihelion Coma Composition of the Interstellar Comet 3I/ATLAS from Optical Spectroscopy
Ruining Zhao, Xiliang Zhang, Bin Yang +4
We present multi-epoch optical spectroscopy of the interstellar comet 3I/ATLAS obtained between December 2025 and January 2026 (heliocentric distances 1.8-3.3 au), yielding post-pe…
Contemporaneous Optical and Near-Infrared Observations of the Interstellar Comet 3I/ATLAS Pre- and Post-Perihelion
Kyle Medler, Willem B. Hoogendam, Christopher Ashall +12
Interstellar objects provide a unique view into the formation of other star systems. Here we present spectroscopic observations of the recently discovered interstellar object 3I/AT…
Interstellar Object 3I/ATLAS Observed from Mars by China's Tianwen-1 Spacecraft
Xin Ren, Wei Yan, Ruining Zhao +20
China's Tianwen-1 Mars orbiter successfully imaged the third interstellar object, 3I/ATLAS, during its close encounter with Mars using the onboard HiRIC CMOS camera. This is China'…
Pre-perihelion radio observations of comet 12P/Pons-Brooks with Tianma radio telescope
Juncen Li, Xian Shi, Jianchun Shi +7
{The multiple outburst events of comet 12P/Pons-Brooks during its 2024 apparition offer a unique window into highly-active volatile releasing processes not observable during quiesc…
Instruct and Extract: Instruction Tuning for On-Demand Information Extraction
Yizhu Jiao, Ming Zhong, Sha Li +4
Large language models with instruction-following capabilities open the door to a wider group of users. However, when it comes to information extraction - a classic task in natural…
Open-Domain Hierarchical Event Schema Induction by Incremental Prompting and Verification
Sha Li, Ruining Zhao, Manling Li +3
Event schemas are a form of world knowledge about the typical progression of events. Recent methods for event schema induction use information extraction systems to construct a lar…
Optical and Near-Infrared Spectroscopy of the Outbursting Comet 12P/Pons-Brooks
Ruining Zhao, Bin Yang, Michael S. P. Kelley +4
We present optical and near-infrared (NIR) observations of the outbursting, Halley-type comet 12P/Pons-Brooks. Three NIR spectra were obtained during two outbursts in October and N…
