Black hole mass estimation for Active Galactic Nuclei from a new angle

1 code implementation5 Mar 2019 Dalya Baron, Brice Ménard

The scaling relations between supermassive black holes and their host galaxy properties are of fundamental importance in the context black hole-host galaxy co-evolution throughout cosmic time.

The delayed evolution of high-mass white dwarfs: the Q branch and double-white-dwarf mergers

1 code implementation29 May 2019 Sihao Cheng, Jeffrey D. Cummings, Brice Ménard

We show that, in addition to crystallization and merger delays, an $8$-Gyr cooling delay is required on the Q branch, which affects about $7\%$ of high-mass WDs.

Extracting the main trend in a dataset: the Sequencer algorithm

3 code implementations24 Jun 2020 Dalya Baron, Brice Ménard

However, some are challenging to detect as they may be expressed in complex manners.

The thermal and gravitational energy densities in the large-scale structure of the Universe

1 code implementation3 Jul 2020 Yi-Kuan Chiang, Ryu Makiya, Eiichiro Komatsu, Brice Ménard

As cosmic structures form, matter density fluctuations collapse gravitationally and baryonic matter is shock-heated and thermalized.

Sequencing seismograms: A panoptic view of scattering in the core-mantle boundary region

no code implementations18 Jul 2020 Do-Yeon Kim, Vedran Lekic, Brice Ménard, Dalya Baron, Manuchehr Taghizadeh-Popp

In nearly half of the diffracting waveforms, we detected seismic waves scattered by three-dimensional structures near the core-mantle boundary.

How to quantify fields or textures? A guide to the scattering transform

no code implementations30 Nov 2021 Sihao Cheng, Brice Ménard

Extracting information from stochastic fields or textures is a ubiquitous task in science, from exploratory data analysis to classification and parameter estimation.

Scattering Spectra Models for Physics

no code implementations29 Jun 2023 Sihao Cheng, Rudy Morel, Erwan Allys, Brice Ménard, Stéphane Mallat

In this paper, we introduce scattering spectra models for stationary fields and we show that they provide accurate and robust statistical descriptions of a wide range of fields encountered in physics.
