Robust inference of the Galactic centre gamma-ray excess spatial properties

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Deheng Song, Christopher Eckner, Chris Gordon, Francesca Calore, Oscar Macias | Summary: The gamma-ray Fermi-LAT Galactic centre excess (GCE) has puzzled scientists for over 15 years. Despite ongoing debates about its properties, and especially its spatial distribution, its nature remains elusive. We scrutinize how the estimated spatial […]

A short proof for Rankin–Cohen brackets and generating operators

Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Toshiyuki Kobayashi, Michael Pevzner, , , | Summary: Motivated by the concept of lqlq{generating operators}rqrq for a countable family of operators introduced in the recent paper (arXiv:2306.16800), we find a method to reconstruct the Rankin–Cohen brackets from a very simple multivariable contour integral, and obtain a new […]

The AGORA High-resolution Galaxy Simulations Comparison Project. VI. Similarities and Differences in the Circumgalactic Medium

Kavli Affiliate: Tom Abel | First 5 Authors: Clayton Strawn, Santi Roca-Fàbrega, Joel R. Primack, Ji-hoon Kim, Anna Genina | Summary: We analyze the circumgalactic medium (CGM) for eight commonly-used cosmological codes in the AGORA collaboration. The codes are calibrated to use identical initial conditions, cosmology, heating and cooling, and star formation thresholds, but each […]

On the evolution of the observed Mass-to-Length relationship for star-forming filaments

Kavli Affiliate: Susan E. Clark | First 5 Authors: Jiancheng Feng, Rowan J. Smith, Alvaro Hacar, Susan E. Clark, Daniel Seifried | Summary: The interstellar medium is threaded by a hierarchy of filaments from large scales (~ 100 pc) to small scales (~ 0.1pc). The masses and lengths of these nested structures may reveal important […]

Opening the AI black box: program synthesis via mechanistic interpretability

Kavli Affiliate: Max Tegmark | First 5 Authors: Eric J. Michaud, Isaac Liao, Vedang Lad, Ziming Liu, Anish Mudide | Summary: We present MIPS, a novel method for program synthesis based on automated mechanistic interpretability of neural networks trained to perform the desired task, auto-distilling the learned algorithm into Python code. We test MIPS on […]
