Compression-Driven Kinetic Instabilities in Magnetically Arrested Disks

Dit artikel presenteert 2D-deeltjes-simulaties die aantonen dat compressie-geïnduceerde drukanisotropie in magnetisch geparkeerde schijven rond zwarte gaten leidt tot cyclotron- en spiegelinstabiliteiten die deeltjes versnellen, waarbij de drempels en evolutie van deze instabiliteiten sterk afhankelijk zijn van de plasma-beta, temperatuur en compressiesnelheid.

Double White Dwarf Mergers as Progenitors of Long-Period Transients

Dit artikel stelt dat de langperiodieke transient GLEAM-X J1627-5235 het resultaat is van een samensmelting van twee witte dwergen, waarbij een model van rotatie-evolutie een leeftijd van ongeveer 572 miljoen jaar voorspelt die consistent is met de waarnemingen en de interpretatie van de bron als een geïsoleerde, snel roterende en sterk gemagnetiseerde witte dwerg-pulsar ondersteunt.

Multi-epoch afterglow rebrightenings in GRB 250129A: Evidence for successive shock interactions

Dit artikel analyseert de multi-epoch heropflaringen in GRB 250129A en concludeert dat deze het beste worden verklaard door opeenvolgende schokinteracties van vertraagde botsingen tussen relativistische schillen, in plaats van door een enkelvoudige externe schok of een eenmalige energie-injectie.

LeMMINGs VII: 5 GHz, 50 mas e-MERLIN observations of a statistically complete sample of nearby AGN

Dit artikel presenteert de diepste statistisch complete radio-bandsurvey van het lokale universum, waarbij 5 GHz e-MERLIN-observaties aantonen dat compacte kernstraling van zwakke actieve galactische kernen (AGN) de primaire vorm van zwarte-gatenactiviteit is, met een detectiepercentage van tot 30% van de lokale populatie, voornamelijk in vroege type-galaxieën.

The Non Parametric Reconstruction of Binary Black Hole Mass Evolution from GWTC-4.0 Gravitational Wave Catalog

Deze studie presenteert een niet-parametrisch raamwerk dat, gebaseerd op de GWTC-3 en GWTC-4 catalogi van LIGO-Virgo-KAGRA, voor het eerst indicaties vindt van een lineaire evolutie in de massa-verdeling van zware dubbele zwarte gaten (m > 50 M☉) naarmate het universum ouder wordt, terwijl lichtere systemen geen dergelijke evolutie vertonen.

Effects of dark dipole radiation on eccentric supermassive black hole binary inspirals

Dit artikel onderzoekt hoe donkere dipoolstraling van excentrische supermassieve zwarte gatenparen de inspiratie kan versnellen en het lage-frequentie spectrum van het stochastic gravitatiegolvenachtergrond beïnvloedt, waarbij een Bayesiaanse analyse met pulsartimingarray-data aangeeft dat dit het lage-frequentie spectrum kan veranderen, hoewel het het laatste-parsec-probleem niet volledig oplost.

Deze studie rapporteert de eerste detectie van ultra-hoge-energie gammastraling (>100 TeV) vanuit het gamma-ray binary-systeem LS I +61 303 met behulp van LHAASO-data, wat sterke aanwijzingen biedt voor extreme deeltjesversnelling en een samengesteld scenario van leptonische en hadronische processen.

Covariance spectrum of MAXI J1820+070: On the nature of the Comptonizing flow

Deze studie analyseert het covariantiespectrum van de zwarte-gat-röntgenbinaire MAXI J1820+070 en onthult dat variabiliteit op korte tijdschalen afkomstig is van een verheven, centraal gelegen Comptoniserend gebied dat wordt verlicht door koelere schijfphotons, terwijl variabiliteit op lange tijdschalen uit een groter gebied komt met een hogere elektronentemperatuur, wat de waargenomen daling in coherentie boven 30 keV verklaart.
