Donald Trump recently said Canada could freely participate in his Golden Dome in exchange for annexation. The US president’s post came on the heels of Mark Carney expressing interest in the missile ‘defense’ initiative, betraying his election promise to distance Canada from the US.
Take a minute to email Carney and defence minister David McGuinty to reject Canadian participation in Trump’s Golden Dome.

"Hard to believe, but it has been already almost 20 years since the days when Apple plastered the halls of its Worldwide Developer Conference (WWDC) with huge posters proclaiming “Redmond, start your photocopiers” or “Mac OS X Leopard: Hasta la vista, Vista”. The decade of the 2000s, coinciding with Steve Ballmer’s tenure as CEO, is widely perceived as a lost one for Microsoft, and one of the most visible signs of that decline was, without a doubt, the “Longhorn” saga."

All-sky search for individual Primordial Black Hole bursts with LHAASO
Primordial Black Holes~(PBHs) are hypothetical black holes with a wide range of masses that formed in the early universe. As a result, they may play an important cosmological role and provide a unique probe of the early universe. A PBH with an initial mass of approximately $10^{15}$~g is expected to explode today in a final burst of Hawking radiation. In this work, we conduct an all-sky search for individual PBH burst events using the data collected from March 2021 to July 2024 by the Water Che…

Fredrik Nyströms påståenden om träning och hälsa - en granskning https://traningslara.se/fredrik-nystroms-pastaenden-om-traning-och-halsa-en-granskning/

Fredrik Nyströms påståenden om träning och hälsa - en granskning
För några dagar sedan publicerades en artikel i Göteborgs-Posten med titeln Läkaren Fredrik Nyström varnar för att vi tränar oss till döds. I artikeln görs ganska många kontroversiella påståenden kring träning, kost och hälsa så jag tänkte att det skulle passa med en liten granskning. För den som har följt mig genom åren ät Fredrik […]

EDEN: Exploring Disks Embedded in N-body simulations of Milky-Way-mass halos from Symphony
We investigate the impact of galactic disks on the tidal stripping of cold dark matter subhalos within Milky Way (MW)-mass halos ($M_{\rm vir}\sim 10^{12}\mathrm{M_{\odot}}$) using a new simulation suite, EDEN. By re-simulating 45 MW-mass zoom-in halos from the N-body Symphony compilation with embedded disk potentials, which evolve according to star formation histories predicted by the UniverseMachine model, we self-consistently tie disk growth to halo accretion rate and significantly expand th…

Guten Morgen,
wie befürchtet, etwas Süßes vor dem Schlafengehen gegessen und nachts um drei hellwach. Eigentlich wüßte ich es.😶
Heute Arbeit, ein Brückentag. Ich mag es, wenn die dreiviertelte Firma frei hat und ich meine Ruhe😙 . Da kann ich Dinge erledigen, die einen längeren Zeitraum an Konzentration erfordern.
So, schönen Freitag, wer arbeiten muß, wer nicht, der/dem auch :-)

Stellar Mass Segregation in Dark Matter Halos

Stellar Mass Segregation in Dark Matter Halos
We study the effect of stellar mass segregation driven by collisional relaxation within the potential well of a smooth dark matter halo. This effect is of particular relevance for old stellar systems with short crossing times, where small collisional perturbations accumulate over many dynamical time scales. We run collisional $N$-body simulations tailored to the ambiguous stellar systems Ursa Major 3/Unions 1, Delve 1 and Eridanus 3, modelling their stellar populations as two-component systems …

The idea is to provide a safe haven and a fertile ground for the next generation of scientists to work in peace and freedom to solve the most significant challenges of our time; but the geopolitical argument will prevail. As Jorge Luis Borges said in his short story “Nathaniel Hawthorne” from his book “Other Inquisitions” (1952):
“The past is indestructible; sooner or later all things return, and one of the things that return is the project to abolish the past.”

There was a moment in which Kurt Gödel, Albert Einstein, and John von Neumann were all roaming the halls of the Institute for Advanced Studies in Princeton at the same time. Let that information sink in. Humanity experiences such gatherings of brilliant minds in a remote location of the space-time continuum only every so often; maybe the ancient Greeks and the men of the Renaissance witnessed such periods in time, as did the IAS staff at the end of World War II. How much will we have to wait f…

The Growth of Galaxy Stellar Haloes Over $0.2 \leq z \leq 1.1$
Galaxies are predicted to assemble their stellar haloes through the accretion of stellar material from interactions with their cosmic environment. Observations that trace stellar halo buildup probe the processes that drive galaxy size and stellar mass growth. We investigate stellar halo assembly over $0.2 \leq z \leq 1.1$ in a mass-complete ($M_{\star} \geq 10^{9.5}M_{\odot}$) sample of 242,456 star-forming and 88,421 quiescent galaxies (SFGs and QGs) from the CLAUDS and HSC-SSP surveys. We ext…
