First Pre-peak Ultraviolet Spectrum of a Tidal Disruption Event: A Fast Outflow Revealed Prior to Maximum Light in TDE2025aarm
Erica Hammerstein, Ryan Chornock, Jean Somalwar +32
The tidal disruption and eventual accretion of a star by a massive black hole can lead to the launching of outflows and winds that encode important information about the tidal disr…
ZTF SN Ia DR2: Colour standardisation of Type Ia Supernovae and its dependence on environment
M. Ginolin, M. Rigault, Y. Copin +37
As type Ia supernova (SN Ia) cosmology transitions from a statistics-dominated to a systematics-dominated era, it is crucial to understand the remaining unexplained uncertainties t…
nbi: the Astronomer's Package for Neural Posterior Estimation
Keming Zhang, Joshua S. Bloom, Stéfan van der Walt +1
Despite the promise of Neural Posterior Estimation (NPE) methods in astronomy, the adaptation of NPE into the routine inference workflow has been slow. We identify three critical i…
Volumetric rates of Luminous Red Novae and Intermediate Luminosity Red Transients with the Zwicky Transient Facility
Viraj R. Karambelkar, Mansi M. Kasliwal, Nadejda Blagorodnova +27
Luminous red novae (LRNe) are transients characterized by low luminosities and expansion velocities, and are associated with mergers or common envelope ejections in stellar binarie…
HEALPix Alchemy: Fast All-Sky Geometry and Image Arithmetic in a Relational Database for Multimessenger Astronomy Brokers
Leo P. Singer, B. Parazin, Michael W. Coughlin +4
Efficient searches for electromagnetic counterparts to gravitational wave, high-energy neutrino, and gamma-ray burst events demand rapid processing of image arithmetic and geometry…
Phenomenological classification of the Zwicky Transient Facility astronomical event alerts
Dmitry A. Duev, Stéfan J. van der Walt
The Zwicky Transient Facility (ZTF), a state-of-the-art optical robotic sky survey, registers on the order of a million transient events - such as supernova explosions, changes in…
A recurrent neural network for classification of unevenly sampled variable stars
Brett Naul, Joshua S. Bloom, Fernando Pérez +1
Astronomical surveys of celestial sources produce streams of noisy time series measuring flux versus time ("light curves"). Unlike in many other physical domains, however, large (a…
cesium: Open-Source Platform for Time-Series Inference
Brett Naul, Stéfan van der Walt, Arien Crellin-Quick +2
Inference on time series data is a common requirement in many scientific disciplines and internet of things (IoT) applications, yet there are few resources available to domain scie…
Evaluating the accuracy of diffusion MRI models in white matter
Ariel Rokem, Jason D. Yeatman, Franco Pestilli +4
Models of diffusion MRI within a voxel are useful for making inferences about the properties of the tissue and inferring fiber orientation distribution used by tractography algorit…
