BlackHolistic 2026: black holes, accretion and jets across the mass spectrum

BlackHolistic 2026 will focus on black hole accretion and jet formation across a wide range of masses and accretion rates, bring together diverse fields from X-ray binaries and transients to AGN and cosmological simulations. The meeting aims to foster cross-disciplinary dialogue and fresh perspectives on the universal physics of accreting black holes.

Highly Accreting Supermassive Black Holes Across all Cosmic Times: from the Local Universe to Cosmic Dawn

Highly Accreting Supermassive Black Holes Across all Cosmic Times will explore the role of highly accreting supermassive black holes in galaxy evolution across cosmic time, from the local universe to the epoch of reionization. It aims to connect observational and theoretical insights into black hole growth, feedback, and their interplay with host galaxies, leveraging data from current and upcoming facilities.

XRISM International Conference 2025

XRISM International Conference will showcase the scientific results from the mission's first two years and outline key issues for future observation cycles. Topics will also include theoretical developments relevant to XRISM data and synergies with other current and upcoming observatories.

Massive Black Holes across Cosmic Time

Massive Black Holes across Cosmic Time brings together observers and theorists to explore the formation, growth, and impact of massive black holes across cosmic time, with a focus on new insights from JWST and multiwavelength data. Key topics include black hole demographics, mass measurements, feedback mechanisms, and the role of accretion in shaping galaxy evolution.

Tracing Cosmic Evolution with Galaxy Clusters - V

The fifth edition of the conference on cosmic structure evolution will take place at the Sexten Center for Astrophysics. The event will focus on topics including galaxy evolution from protoclusters to massive clusters, the cosmic history of baryons, gravitational lensing, and cosmology with next-generation cluster surveys.

Vasto Accretion Meeting: AGN

Vasto Accretion Meeting: AGN will explore the understanding of AGN, both their intrinsic continuum and the wind and jets which they launch, and how all these change with black hole mass, mass accretion rate and across cosmic time.

Unleashing the Power: Linking the Small and the Large in Multi-phase AGN Outflows

Feedback from active galactic nuclei (AGN) in the form of jets and outflows is a key ingredient in galaxy evolution models. The "Unleashing the Power: Linking the Small and the Large in Multi-phase AGN Outflows" special session at EAS 2025 will bring together both observations and simulations investigating all types of AGN outflows.

XMM Data Analysis Workshop

The workshop aims to improve the accessibility and usability of XMM data and its analysis tools, with sessions for both beginners and experienced users. It offers an introduction to the Science Analysis Software (SAS), Extended Source Analysis System (ESAS), and the XMM archive through Python notebooks and SciServer, including a discussion on contributing to pySAS development.

Celebrating 20 years of Swift Discoveries

Launched in 2004 to study Gamma-Ray Bursts, Swift has since exceeded its goals, becoming an essential tool for transient astronomy with its rapid response and multi-wavelength capabilities. The "Celebrating 20 Years of Swift Discoveries" conference will revisit Swift's groundbreaking contributions to time-domain and multi-messenger astrophysics.
