title: Remotely Sensed Tree Mortality Rates in Mesic Forests of the US Southwest During an Extended Drought

description: Abstract 




Persistent drought since the early 2000s has increased forest vulnerability to disturbances such as insect outbreaks, wildfire, and climate-induced tree die-off events across the western United States (US). Mesic forests of the US Southwest, characterized by geographic and climatic isolation and rich biodiversity, face heightened risks due to limited connectivity with similar forest ecosystems, restricted population migration potential, and upslope range contraction of high-elevation tree species. We manually interpreted high-resolution aerial imagery from 1076 forest stands to quantify recent tree mortality due to insect outbreaks and drought in isolated, mesic forests of the Southwest, then combined these data with Landsat time series and Random Forest (RF) modeling to create a 30-m map of cumulative mortality (i.e., percentage of initial canopy cover that died) from 1997 to 2023. Consistent with prior research, changes in shortwave infrared reflectance (e.g., 1.55–1.75 μm) were the best predictors of tree mortality. Overall mortality rates (0.4 % canopy cover year -1) were comparable to field-derived rates of background mortality for large trees throughout the western US (i.e., 0.5 – 2 % year -1). Low mortality (< 30 %; < 1 % year -1) occurred in 94 % of the total area, while higher mortality (> 80 %; > 2.5 % year -1) occurred in fragmented, high-elevation patches. Notably, the RF model had low-to-moderate accuracy (R² = 0.28, RMSE = 18 % mortality), and some forest management and fire occurrences were difficult to omit from disturbance maps using existing data, highlighting challenges in capturing low-severity disturbance effects using Landsat imagery. Since ca. 2000, wildfire may have been a larger driver of change in mesic forest systems of the US Southwest than drought-caused tree die-off and background mortality. This study emphasizes the need for continued monitoring of background tree mortality rates and provides insights into monitoring change in other vulnerable, isolated forest ecosystems.

title: The Universal Equilibrium Constant (I = 4πGσ / c⁴)

description: We extend previous work on the photogravitational ratio

Φ = L / (M g)

by introducing a new invariant quantity that reveals a fundamental constant of nature:

 

I = (Φ β²) / (T⁴ R²) = 4 π G σ / c⁴ = 5.888 × 10⁻⁵¹ m⁻¹ s⁻¹ K⁻⁴

 

Building upon the established photogravitational framework, where Φ quantifies the balance between radiation and gravity, we show that this combination yields a universal constant equal to 4 π G σ / c⁴.

This invariant links radiative equilibrium, Newtonian gravity, and relativistic compactness, demonstrating that all thermal, optically thick photospheres—from main-sequence stars to neutron stars and formally to black holes—obey the same equilibrium condition.

 

The discovery of this universal constant reduces the independent stellar observables (L, M, R, T) from four to three, revealing that classical equilibrium laws—Stefan–Boltzmann, Eddington, Kelvin–Helmholtz, and Hawking—are not independent relations but algebraic projections of a single identity.

The constant bridges microscopic physical constants (G, σ, c) and macroscopic observables, establishing photospheres as geometric–thermodynamic boundaries of spacetime.

 

Empirical verification across 23 orders of magnitude in mass—from the Sun, Sirius A, Vega, and Wolf–Rayet 124 to theoretical compact objects—confirms invariance within measurement uncertainties.

In Wolf–Rayet stars, the photogravitational parameter Φ clusters by subtype (±10 %), allowing direct mass determination from (L, R) alone and revealing a systematic ≈43 % mass deficit relative to evolutionary models.

This equilibrium constant provides a unified, falsifiable framework linking gravity, radiation, and thermodynamics across nature.

title: Parkes observations for project P1054 semester 2025OCTS_02

description: With this proposal we ask time to continue our timing follow-up campaign of pulsars discovered with the MeerKAT telescope. Fourtyfour sources have been discovered in targeted observations of Fermi unidentified point sources, two towards Supernova Remnants, 26 in the Magellanic Clouds, 106 in Globular Clusters and 87 in a survey of the Galactic plane. A large fraction of the new discoveries are recycled pulsars (including a few relativistic systems, a pulsar with a planetary companion and several 'spider' binaries), or young pulsars. Timing observations have an essential role in exploiting the full potential of any pulsar discovery, allowing for the precise measurement of rotational, astrometric and orbital parameters which, in turn, give us powerful tools to improve our understanding of the physics in extreme environments as well as of the population of neutron stars as a whole. The UWL receiver of the Parkes telescope is a sensitive, versatile instrument that is allowing us to successfully time these new sources, in the bright-end of TRAPUM discoveries.

title: Parkes observations for project P1381 semester 2025OCTS_01

description: The Galactic bulge is theorized to host a rich population of millisecond pulsars (MSPs), but direct detections have been severely hampered by high interstellar scattering, dispersion, and background noise near the Galactic center. These MSPs, if confirmed, would serve as powerful tools for testing gravity, studying dense matter, and probing gravitational waves. A key indirect tracer of this population is the Fermi GeV excess (FGE), an unresolved gamma-ray signal possibly originating from thousands of faint MSPs. However, the lack of direct detections has limited our ability to test this hypothesis.
 The MeerKAT Galactic Bulge Survey (MGBS) is the most sensitive pulsar search yet of this region, targeting the bulge MSP population. Early results from MGBS have already revealed several promising MSP candidates. We propose to use Murriyang to conduct targeted follow-up observations of three of the most compelling candidates from MGBS. Our goals are to confirm the pulsations, refine key parameters such as spectral indices and orbital characteristics, and strengthen their association with the bulge.
 Confirming even a handful of bulge MSPs would have wide-reaching impact: constraining the origin of the FGE, testing dark matter interpretations, refining models of Galactic structure, and improving predictions for low-frequency gravitational wave backgrounds. This proposal is a critical next step toward establishing a long-sought bulge MSP population and unlocking new physics from the inner Galaxy.

description: UNITE provides a unified way for delimiting, identifying, communicating, and working with DNA-based Species Hypotheses (SH). All fungal ITS sequences in the international nucleotide sequence databases are clustered to approximately the species level by applying a set of dynamic distance values (<0.5 - 3.0%). All species hypotheses are given a unique, stable name in the form of a DOI, and their taxonomic and ecological annotations are verified through distributed, web-based third-party annotation efforts. SHs are connected to a taxon name and its classification as far as possible (phylum, class, order, etc.) by taking into account identifications for all sequences in the SH. An automatically or manually designated sequence is chosen to represent each such SH. These sequences are released (https://unite.ut.ee/repository.php) for use by the scientific community in, for example, local sequence similarity searches and next-generation sequencing analysis pipelines. The system and the data are updated automatically as the number of public fungal ITS sequences grows.
