The Next Generation of High-z Cluster Studies (Anthony Flores)
The Intracluster Medium (ICM) encodes the integrated history of cosmic feedback processes from the formation of their host systems to the moment of observations. In order to determine the profound effects Active Galactic Nuclei and Star Formation processes have on the evolution of galaxy clusters, we require spatially resolved X-ray measurements of the ICM out to high-z. While the current generation of X-ray instruments (Chandra+XMM-Newton) have provided crucial insights into cluster evolution at low-to-intermediate redshifts, they struggle significantly at high redshift where both high spatial resolution and soft sensitivity are required to fully characterize these systems. The Advanced X-ray Imaging Satellite (AXIS) will revolutionize the field of high-z cluster science, extending thermodynamic and chemical measurements of the ICM into the period of Cosmic Noon and placing tight constraints on when and how AGN and SF processes influenced the evolution of the most massive objects in the Universe.

The cross-talk between global dynamics in the ICM/CGM and microphysics (Prakriti Palchoudhury)
Переглядів 323 місяці тому
Diffuse, weakly collisional and weakly magnetised intracluster and circumgalactic media are not only crucial to understand the large scale galaxy formation physics across redshifts, but these are also ideal testbeds for exploring effects of plasma scale transport phenomena. The important X-ray observational probes include (not exhaustively) (i) Strong shock sites that can hint at Coulomb collis...
Insights into Early SMBH Growth from JWST (Dale Kocevski)
Переглядів 543 місяці тому
The capabilities of JWST are now allowing us to measure the host demographics of AGN beyond cosmic noon and detect lower luminosity quasars out to the epoch of reionization. I will discuss recent AGN-related results from the CEERS Survey and what they tell us about the growth of SMBHs in the early universe. This includes the discovery of an actively accreting SMBH at z=8.67, which is one of the...
Chasing X-ray counterparts to Fast Radio Bursts and Hypernebula with AXIS (Navin Sridhar)
Переглядів 464 місяці тому
Fast Radio Bursts are a new class of ms-duration coherent radio flashes, mostly of extragalactic origin. In April 2020, an FRB was detected from a Galactic magnetar, contemporaneous with a brief X-ray flash. A couple of years later, the same source produced an FRB contemporaneous with the largest spin glitch seen in a magnetar as monitored from the quasi-periodic X-ray bursts. These observation...
Time-domain and Multi-messenger Science with Supermassive Black Hole Binaries (Tingting Liu)
Переглядів 394 місяці тому
A supermassive black hole binary (SMBHB) is thought to form at the final stage of a galaxy merger when the two SMBHs are sufficiently close to become gravitationally bound, before gravitational radiation brings the SMBHs to coalescence. Last year, the pulsar timing array (PTA) collaborations announced evidence for a stochastic gravitational-wave (GW) background that is consistent with expectati...

I examine AXIS's ability to examine extended stellar atmospheres. The stellar atmosphere extends tens of AU from the stellar surface and planets spend their entire existence within the turbulent stellar atmosphere. The atmosphere starts with coronal structures on the star which give rise to the winds that fill the space beyond with ionized high-velocity particles. These winds are complicated by...
AXIS view of Planetary Nebulae Hot Bubble Plasmas (Rudolf Montez)

    There is no black holes. General Relativity predicts dilation, not singularities. In the 1939 journal "Annals of Mathematics" Einstein wrote - "The essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of General Relativity predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters (star clusters) whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light." He was referring to the phenomenon of dilation (sometimes called gamma or y) mass that is dilated is smeared through spacetime relative to an outside observer. It's the phenomenon behind the phrase "mass becomes infinite at the speed of light". Time dilation is just one aspect of dilation, it's not just time that gets dilated. A graph illustrates its squared nature, dilation increases at an exponential rate the closer you get to the speed of light. Dilation will occur wherever there is an astronomical quantity of mass because high mass means high momentum. There is no singularity at the center of our galaxy. It can be inferred mathematically that dilation is occurring there. This means that there is no valid XYZ coordinate we can attribute to it, you can't point your finger at something that is smeared through spacetime. More precisely, everywhere you point is equally valid. This is the explanation for dark matter. The "missing mass" is dilated mass. Dilation does not occur in galaxies with low mass centers because they do not have enough mass to achieve relativistic velocities. To date, 6 very low mass galaxies including NGC 1052-DF2 and DF4 have been confirmed to show no signs of dark matter. This also explains why all planets and all binary stars have normal rotation rates, not 3 times normal.

    bro the earth is not a planet. how do you see venus at night? think about it. The eccencricity of orbit for earth and venus is closest to a circle we should not see venus at night we are looking away from the sun and venus is between the sun and earth. Or so you've been told. there is no way to independently check we have to take the word of NASA and or the military since that is who controls the information you think is real. The earth is the endless universe it is an endless plane (no edge no dome no continuous icewall but more land more continents)(look into the 1907 kobayashi map extra continents map). look into it look past the surface level gatekeeping and you will see that we have been lied to since elementary school. Please read "kings dethroned" or listen to the audio book. everything you think you know about space is a lie or misinfo or disinfo. There is more land more continents unlimited resources. flat earthers are a strawman attack a psyop of misinfo to hide the truth I am not religious I want to believe space is what Ive been told but it isnt. look into it as a skeptic the old nasa footage is all garbage obvious green or blue screen really terrible effects.
