Anisotropy ansatz for the axisymmetric Jeans equations

Anisotropy ansatz for the axisymmetric Jeans equations
The Jeans equations do not form a closed system, and to solve them a parametrization relating the velocity moments is often adopted. For axisymmetric models, a phenomenological choice (the "$b$-ansatz") is widely used for the relation between the vertical ($σ_z^2$) and radial ($σ_R^2$) components of the velocity dispersion tensor, thus breaking their identity present in two-integral systems. However, the way in which the ansatz affects the resulting kinematical fields can be quite complicated…

Works by women artists from before the 19th century are usually rare in museum collections. See #LindaNochlin and the #GuerrillaGirls for thoughts on why. We just acquired a gorgeous little Holy Family painting from an artist in the circle of Lavinia Fontana (1552 Bologna – 1614 Rome), a 16th/17th-c…

Bernardo Dessau, fisico, scienziato, maestro, da Bologna a Perugia tra i marosi del secolo breve
Seventy-five years ago, Bernardo Dessau passed away. He had been the sole professor of Physics at the University of Perugia for thirty years. With this brief contribution we intend to repay a debt of gratitude, first of all because his scientific merits were probably underestimated, having spent the first fifteen years of his career under the shadow of the great Augusto Righi in Bologna, where he also witnessed meetings with the young Marconi. He was then relegated to the Faculty of Medicine of…

Il sapere delle lotte | il manifesto
(Cultura) 60 anni fa il primo numero di «Classe Operaia», uno dei laboratori dell’operaismo che anticipò molte delle attuali riflessioni sui lavoratori della conoscenza e l’annuncio dell’intelligenza artificiale. Di Sergio Fontegher Bologna

Gründe Wien zu meiden: Furcht vor'm kühlen Klima - so begründete zumindest 1704 der Bologneser Maler Marcantonio Franceschini seine Ablehnung, das Liechtensteinsche Gartenpalais mit Fresken auszustatten. Er fertigte seine Malereien lieber in Bologna an und schickte sie nach Wien. Quelle: Raumtext, Palais Liechtenstein

Time and frequency transfers in optical spacetime
Solving the null geodesic equations for a ray of light is a difficult task even considering a stationary spacetime. The problem becomes even more difficult if the electromagnetic signal propagates through a flowing optical medium. Indeed, because of the interaction between light and matter, the signal does not follow a null geodesic path of the spacetime metric anymore. However, having a clear description of how the time and frequency transfers are affected in this very situation is of a prime …

Colored Stochastic Multiplicative Processes with Additive Noise Unveil a Third-Order PDE, Defying Conventional FPE and Fick-Law Paradigms
Research on stochastic differential equations (SDE) involving both additive and multiplicative noise has been extensive. In situations where the primary process is driven by a multiplicative stochastic process, additive white noise typically represents an intrinsic and unavoidable fast factor, including phenomena like thermal fluctuations, inherent uncertainties in measurement processes, or rapid wind forcing in ocean dynamics. This work focuses on a significant class of such systems, particula…

The longevity of the oldest open clusters: Structural parameters of NGC 188, NGC 2420, NGC 2425, NGC 2682, NGC 6791, NGC 6819
Context: Open clusters' dynamical evolution is driven by stellar evolution, internal dynamics and external forces, which according to dynamical simulations, will evaporate them in a timescale of about 1 Ga. However, about 10\% of the known open clusters are older. They are special systems whose detailed properties are related to their dynamical evolution and the balance between mechanisms of cluster formation and dissolution. Aims:We investigate the spatial distribution and structural parameter…
