Astrometry.net: Blind astrometric calibration of arbitrary astronomical images

dstndstn/astrometry.net 12 Oct 2009

We have built a reliable and robust system that takes as input an astronomical image, and returns as output the pointing, scale, and orientation of that image (the astrometric calibration or WCS information).

Long-lasting high state of the high-field polar AR UMa

MickaelRigault/ztfquery 23 May 2023

Before entering the current long-lasting high state, this object showed three short-lived high states, which might have been precursors to the current state.

Boosting Supermassive Black Hole Growth in the Early Universe by Fuzzy Dark Matter Solitons

gamer-project/gamer 15 Jan 2025

We then demonstrate using hydrodynamic simulations that, compared to cold dark matter, these high-$z$ massive FDM solitons with mass $M_s$ can provide additional gravitational potential to accrete gas and boost the Bondi accretion rate of a growing black hole seed with mass $M_{\rm BH}$ by up to two to four orders of magnitude, in the regime of efficient cooling and negligible radiation pressure.

ESA-Ariel Data Challenge NeurIPS 2022: Introduction to exo-atmospheric studies and presentation of the Atmospheric Big Challenge (ABC) Database

ucl-exoplanets/TauREx_public 29 Jun 2022

In this paper, We present the Atmospheric Big Challenge Database (ABC Database), a carefully designed, organised and publicly available database dedicated to the study of the inverse problem in the context of exoplanetary studies.

Faceting for direction-dependent spectral deconvolution

mhardcastle/ddf-pipeline 6 Dec 2017

In this paper we discuss and implement a wide-band wide-field spectral deconvolution framework (DDFacet) based on image plane faceting, that takes into account generic direction-dependent effects.

Finding counterparts for All-sky X-ray surveys with Nway: a Bayesian algorithm for cross-matching multiple catalogues

JohannesBuchner/nway 30 May 2017

We release the AllWISE counterparts and Gaia matches to 106, 573 and 17, 665 X-ray sources detected in the ROSAT 2RXS and XMMSL2 surveys with |b|>15.

Efficient sampling of fast and slow cosmological parameters

cmbant/CosmoMC 16 Apr 2013

I describe a method for decorrelating fast and slow parameters so that parameter sampling in the full space becomes almost as efficient as sampling in the slow subspace when the covariance is well known and the distributions are simple.

Constraints on the Abundance of PBHs from X-ray Quasar Microlensing Observations: Substellar to Planetary Mass Range

bradkav/PBHbounds 14 Jul 2023

We use X-ray observations of quasar microlensing (sensitive to smaller compact objects than in the optical) to study the possible presence of a population of low mass black holes (from $\sim$ $10^{-3}M_{\odot}$ to $10^{-1}M_{\odot}$) in lens galaxies.
