There seem to be constant reminders of the disastrous mistakes that led up to the most catastrophic American foreign policy decision in recent memory -- the war on Iraq.
Despite the costly lessons of the past and the flashing warning signs before us today,
Trump seems poised to press the button on joining Israel’s attack on Iran.
Doing so could be an even bigger mistake.
The echoes are numerous:
A complete disregard for international law and diplomatic alternativ…

Can the United States Really Be Marching Toward This Madness Again?
The eerie echoes of Iraq and 2003 are numerous. But there are some key differences—and they make going into Iran an even greater act of folly.

There are far more ways for an air strike on Iran to go wrong than for it to go the way it is being sold to Trump.
The illegal attack launched by Israel against Iran already set off a war that raises the stakes -- and brings the U.S. increasingly closer to getting directly involved -- even if it doesn’t strike.
But if it does strike, it sets off a series of consequences that likely lead to a long, drawn-out commitment with no clear exit strategy, again.
An American strike…

Quasi-normal modes and echoes of generalized black hole bounces and their correspondence with shadows

Quasi-normal modes and echoes of generalized black hole bounces and their correspondence with shadows
We study the quasi-normal modes (QNMs) of a family of generalized black bounces interpolating between regular black holes and traversable wormhole solutions according to a single extra parameter $a$. Firstly, working with a generic spherically symmetric space-time with arbitrary radial function and an anisotropic fluid matter source, the general equations for the gravitational waves are obtained. Then, we focus on such particular space-time metric and use the time-domain method to find the evol…

Fascism is not some distant nightmare locked away in history books. It is a dark, living force that haunts the present, casting its shadow over the United States with terrifying clarity.
The brutal dehumanization, the cruelty inflicted on vulnerable people, the aggressive nationalism and racism, these are not echoes from the past but the harsh reality of today. Concentration camps for children, hateful rhetoric that strips away humanity, and the rise of authoritarian power show that fa…

Unraveling Freeze-in Dark matter through the echoes of gravitational waves
In the quest to unravel the dark sector, feebly interacting freeze-in dark matter presents an intriguing possibility, plausibly explaining the consistent null results from various dark matter experiments. We propose a unique imprint in the form of gravitational waves generated during the freeze-in production of dark matter from heavy particle decay in the early universe. This characteristic gravitational wave signature can serve as a powerful probe for freeze-in dark matter. Our study indicates…

Contrast-Invariant Self-supervised Segmentation for Quantitative Placental MRI
Accurate placental segmentation is essential for quantitative analysis of the placenta. However, this task is particularly challenging in T2*-weighted placental imaging due to: (1) weak and inconsistent boundary contrast across individual echoes; (2) the absence of manual ground truth annotations for all echo times; and (3) motion artifacts across echoes caused by fetal and maternal movement. In this work, we propose a contrast-augmented segmentation framework that leverages complementary infor…

High-precision light curves of geostationary objects: The PHANTOM ECHOES 2 RPO campaign
We present results from an extensive optical observation campaign that monitored the Geostationary satellites Intelsat 10-02, Mission Extension Vehicle 2, Thor 5, Thor 6, Thor 7, and Meteosat 11 over a 14 week period that covered the proximity operations and docking of Mission Extension Vehicle 2 with Intelsat 10-02. High-cadence single-color photometric observations are supplemented with targeted multi-color observations, high resolution imaging, and passive radio frequency positioning obtaine…

JWST's First View of Tidal Disruption Events: Compact, Accretion-Driven Emission Lines & Strong Silicate Emission in an Infrared-selected Sample
Mid-infrared (MIR) emission from tidal disruption events (TDEs) is a powerful probe of the circumnuclear environment around dormant supermassive black holes. This emission arises from the reprocessing of intrinsic emission into thermal MIR emission by circumnuclear dust. While the majority of optical- and X-ray-selected TDEs show only weak dust echoes consistent with primarily unobscured sight lines, there have been growing efforts aimed at finding TDEs in obscured environments using MIR select…

Near-inertial echoes of ageostrophic instability in submesoscale filaments
Ocean submesoscales, flows with characteristic size around 10 m - 10 km, are transitional between the larger, rotationally-constrained mesoscale and three-dimensional turbulence. In this paper we present simulations of a submesoscale ocean filament. In our case, the filament is strongly sheared in both vertical and cross-filament directions and is unstable. Instability indeed dominates the early behaviour with a fast extraction of kinetic energy from the vertically sheared thermal wind. However…

Self-Supervised-ISAR-Net Enables Fast Sparse ISAR Imaging
Numerous sparse inverse synthetic aperture radar (ISAR) imaging methods based on unfolded neural networks have been developed for high-quality image reconstruction with sparse measurements. However, their training typically requires paired ISAR images and echoes, which are often difficult to obtain. Meanwhile, one property can be observed that for a certain sparse measurement configuration of ISAR, when a target is rotated around its center of mass, only the image of the target undergoes the co…

SHARAD Illuminates Deeper Martian Subsurface Structures with a Boost from Very Large Rolls of the MRO Spacecraft
Throughout its mission, the Mars Reconnaissance Orbiter (MRO) has often rolled about its along-track axis by up to 28° to partially compensate for the suboptimal location of the Shallow Radar (SHARAD) antenna along an edge of the spacecraft that is opposite the imaging payload deck, thereby enhancing the signal-to-noise ratio (S/N) of echoes returned from the surface. After recent modeling work predicted that a much larger roll would improve the S/N by ~10 dB relative to nadir-pointed observin…
