Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
2. Earth spin like a top as it circles around the sun.
Earth is tipped to one side as it move. This tilt
causes the changing seasons.
3.
4. Earth seems to be standing still
Do you feel the movement of the earth? Why?
There are two reasons
1. You can’t sense it movement because you are moving
along with it!
2. Another reason that you don’t sense Earth’s motion is
that it moves steadily and smoothly.
5. How do you know that Earth is
moving?
Earth is moving because the Sun and the stars seem to move
across the sky. This happens because the earth is turning.
Another reason is that the seasons change during the year for
most of the places away from the equator.
6. What is an equator?
An equator is the imaginary line that divides the north and
south halves of the Earth.
9. Axis
An axis is an imaginary line that goes through the center
of some things. Earth’s axis passes through the North pole,
center of the earth, and south pole.
11. Rotation
Each time Earth makes a full turn around it axis.
Earth takes 23 hours and 56 minutes to complete one
rotation.
The Earth rotates from west to east so that is the reason
that objects such as Sun and other stars appear to move
from east to west in the sky.
12. Earth’s rotation causes day and night
When Earth rotates different parts of the Earth pass
through the Sun’s light. When a place on the Earth is
turned toward the Sun, it is day. When that place has
rotated away from the Sun, it is night.
13.

15. Earth’s Revolution
What is revolution?
The movement of one
object around another is
called revolution.
Earth revolves around the
sun.
16. What is the difference b/w rotation
and revolution
17. Orbit
The path that Earth or other planets follow as they
revolves around the sun is called it orbit
18. Earth takes 1 year, or about 365 days, to complete 1
revolution.
Ellipse
An ellipse is like a circle stretched out in opposite
direction. Earth’s orbit is elliptical. As Earth moves in its
orbit due to Earth’s elliptical orbit the distance of the
earth changes. Earth is farther from the Sun in some parts
of its orbit. It is closer to the Sun in other parts.
19.
20. Gravity
A force that pull two objects toward each other is called
it Gravity. It can act at a distance. The gravity between
Earth and Sun keeps Earth revolving around the Sun.
With out gravity Earth would fly off into space.
If Earth stopped moving. The attraction b/w Earth and
the Sun would make them crash into each other.
21. Earth’s tilted Axis
Earth’s axis is always tilted. As earth revolves around
the Sun, its axis is always tilted in the same direction.
The end of the axis at the north pole currently points
toward the Polaris, the North Star. This tilt affects how
places on Earth receive sunlight. In different parts of
the Earth’s orbit different places directly face the Sun.
22. In late June, the Northern Hemisphere half the Earth, tilts
toward the Sun. it is summer, and daylight is longer than
night. But it is winter in the southern hemisphere. Night
are longer than day lights.
In late December, the Southern Hemisphere tilts toward
the sun. Now, it is summer in the southern hemisphere
and winter in the Northern.
Earth’s axis is not tilted toward the Sun in spring and fall.
The lengths of daylight and night are more nearly equal
in spring and fall.
